Description

Technical Field

[0001] This invention relates to the field of electrophotographic imaging technology, and more particularly to a processing box. Background Technology

[0002] Existing technology discloses an imaging device and a detachable processing cartridge installed in the imaging device. The processing cartridge includes a first housing, a developing roller, a force receiver, and a separator supported on the first housing, and a photosensitive drum supported on a second housing. When the processing cartridge performs a printing task, the developing roller and the photosensitive drum are in pressure contact with each other, and the developing roller can deliver the developer it carries to the photosensitive drum to develop the electrostatic latent image on the photosensitive drum. When the processing cartridge does not perform a printing task, the force receiver can push the first housing to move relative to the second housing, thereby causing the separator supported on the first housing to move to a position abutting against the second housing. This can stably maintain the separation of the developing roller and the photosensitive drum, preventing the developer on the developing roller of the processing cartridge, which does not perform a printing task, from being continuously delivered to the photosensitive drum, thus affecting the print quality of the processing cartridge. However, when the processing cartridge frequently switches between performing printing tasks and not performing printing tasks, the frequently moving separator may get stuck or fail to move into place, thus affecting the printing process of the processing cartridge.

[0027] Furthermore, the conductive component is configured as a grounding portion of the imaging device, and the processing box has a grounding member that contacts the grounding portion. The grounding member is electrically connected to the developing roller, and the developing roller can switch between a state of being electrically connected to the grounding portion and a state of being electrically disconnected from the grounding portion by the movement of the force receiving member.

[0028] Furthermore, it also includes a chip with a chip electrical contact surface.

[0088] Example 1

[0089] To facilitate the description of the processing cartridge 500 in this invention, the various directions of the processing cartridge 500 will be defined below. The extension direction of the rotation axis of the developing roller 501 (the rotation axis of the developing roller) is the first direction. In the first direction, the housing 510 has a first end and a second end opposite to each other. The first coupling member 521 and the second coupling member 522 are disposed at the first end of the housing 110. The chip electrical contact surface 513a is also disposed at the first end of the housing 510.

[0090] like Figure 1-18 As shown, the present invention discloses a processing box 500, which is detachably installed in an imaging device having a power supply component, electrical contacts, a driving force application component, and a pushing component. In the present invention, the imaging device is an electrophotographic imaging device (printer).

[0091] like Figure 1 As shown, the processing cartridge 500 includes a developing unit and a drum unit connected to each other. The developing unit includes a first housing 510a, and the drum unit includes a second housing 510b. The housing 510 includes the first housing 510a and the second housing 510b. The first housing 510a can contain developer, and the second housing 510b includes a first cover 511 at a first end and a second cover 512 at a second end, and a main body portion 518 located between the first cover 511 and the second cover 512, which can contain waste developer. At least one of the first cover 511 and the second cover 512 is integrally formed with the main body portion 518. This not only reduces the number of molds but also improves assembly efficiency, thereby reducing the production cost of the processing cartridge 500. Furthermore, the first cover 511, the second cover 512, and the main body portion 518 are integrally formed, which can further reduce the production cost of the processing cartridge 500 and improve the assembly efficiency of the processing cartridge 500.

[0092] The developing unit includes a developing roller 501, a powder feeding roller, and a powder discharging blade supported on the first housing 510a. The drum unit also includes a photosensitive drum 502 and a charging component (not shown) supported on the second housing 510b. The charging component is preferably a rotatable charging roller. When the processing cartridge 500 performs a printing operation, the developing roller 501 carries developer, and the charging roller can uniformly charge the photosensitive drum 502. After the charged photosensitive drum 502 is selectively irradiated (exposed) by the laser in the imaging device, an electrostatic latent image can be formed on the outer surface of the photosensitive drum 502. This allows the developing roller to transport the developer carried on the developing roller to the photosensitive drum 502 through contact with the photosensitive drum 102 to develop the electrostatic latent image thereon, thus forming a developer image on the photosensitive drum 502. Subsequently, the developer image can be transferred to the transfer belt of the imaging device through contact between the photosensitive drum 502 and the transfer belt. Finally, the transfer belt can transfer the developer image to a recording medium (such as paper).

[0093] Furthermore, the processing box 500 also includes a first coupling member 521 (first coupling protrusion 521) and a second coupling member 522 (second coupling protrusion 522) disposed at the first end of the housing 510. The first cover 511 can cover at least a portion of the first coupling member 521 and / or the second coupling member 522 to position the first coupling member 521 and / or the second coupling member 522. The first coupling member 521 and the second coupling member 522 can be coupled to the first driving force applying member and the second driving force applying member of the imaging device, respectively, and can receive the rotational driving force output by them to rotate, thereby driving the developing roller 501 and the photosensitive drum 502 to rotate, respectively.

[0094] Furthermore, the processing cartridge 500 also includes a chip 513 and a first electrode 568. The chip 513 has a chip electrical contact surface 513a, and the first electrode 568 has a first electrode electrical contact surface. In the first direction, the chip electrical contact surface 513a is disposed at the first end of the housing 510, that is, at the same end of the housing 510 as the first coupling member 521 or the second coupling member 522 in the first direction. The first electrode electrical contact surface is located at the second end of the housing 510 and is configured as a plane that is approximately perpendicular to the first direction. Therefore, in the first direction, the distance between the two is relatively large, which helps to avoid electrical interference between the first electrode electrical contact surface and the chip electrical contact surface 513a when they are in contact with the imaging device, thereby affecting the printing quality of the processing cartridge 500. In the second direction (vertical direction), the chip electrical contact surface 513a of the chip 513 is located at the upper end of the processing cartridge. Furthermore, the processing box 500 also includes a chip holder 515 for supporting the chip 513. The chip holder 515 is detachably mounted on the first cover 511 of the housing 510. In this way, when the processing box 500 is assembled, the chip 513 and the chip holder 515 can be installed as a chip assembly on the processing box 200. This helps to improve the assembly efficiency of the chip 513 and avoids the problem of difficult assembly of the chip 513 that is too small.

[0095] When the imaging device needs to print black pages, the processing cartridge 500 containing black developer operates normally. During development, the third power supply unit of the imaging device supplies power to the charging roller to charge the photosensitive drum 502. However, the processing cartridge 500 containing color developers (e.g., magenta, yellow, and blue) needs to be inactive to avoid color mixing during printing. To achieve this, in existing processing cartridges, when the processing cartridge containing color developers is not needed for development, the processing cartridge can receive the driving force of the imaging device to separate the developing roller from the photosensitive drum, thus preventing the color developers on the developing roller from being transferred to the photosensitive drum. However, in this embodiment, the developing roller 501 and the photosensitive drum 502 of the processing cartridge 500 are in continuous contact. To prevent the developer on the developing roller 501 from transferring to the photosensitive drum 502 through the potential difference, the processing cartridge 500 further includes a control component. The control component can be used to control the grounding or ungrounding state of the developing roller 501 and the powder feeding roller (not shown in the figure) to suppress the developer carried on the developing roller 501 from transferring to the photosensitive drum 502. Thus, the printing quality of the processing cartridge 500 is not affected when the developing roller 501 and the photosensitive drum 502 are in continuous contact. The structure of the control component will be described in detail below.

[0096] like Figure 2-4As shown, the processing box 500 includes a force receiving member 540 movably disposed on a first housing 510a or a second housing 510b. The force receiving member 540 includes a first force receiving portion 540b1 and a second force receiving portion 540b2. The first force receiving portion 540b1 and the second force receiving portion 540b2 are integrally formed to reduce the number of molds used during production and reduce production costs. However, the first force receiving portion 540b1 and the second force receiving portion 540b2 can still be separate structures. For example, the first force receiving portion 540b1 is disposed in a first unit having a first housing 510a, and the second force receiving portion 540b2 is disposed on the force receiving member 540. This is not a limitation.

[0097] The force receiver 540 can receive external force from the pushing part of the imaging device and can rotate relative to the first housing 510a or the second housing 510b between a first position and a second position. At least a portion of the force receiver 540 in the first position is closer to the photosensitive drum 502 than the force receiver 540 in the second position; further, as... Figure 8-9 As shown, the processing box 500 also includes a pushing protrusion 541, which is configured to protrude outward from the outer surface of the force receiver 540 toward a second end near the housing 510. When the force receiver 540 is moved by the pushing portion of the imaging device, the pushing protrusion 541 can move in response to the movement of the force receiver 540. Furthermore, the pushing protrusion 541 has a pushing ramp 541a intersecting the first direction, which can be used to guide and push the pusher 562 (described in detail below), such that the pusher 562 moves from the first direction... Figure 8 Move to the position shown Figure 9 The position shown; further, the force receiver 540 also includes a retaining portion 540a configured as a protrusion, which can move with the movement of the force receiver 540. When the first force receiver 540b1 receives the pushing force of the pushing portion of the imaging device, causing the force receiver 540 to move from the first position to the second position, the retaining portion 540a also moves. Subsequently, under the control of the imaging device, the pushing portion removes the pushing force applied to the first force receiver 540b1, and the retaining portion 540a abuts against the first housing 510a or the second housing 510b, thereby maintaining the position of the force receiver 540 relative to the housing 510 and preventing the force receiver 540 from moving. During the movement of the force receiver 540, the developing drum 501 and the photosensitive drum 502 will always remain in contact; further, the pushing member 562 is made of a conductive material, which can be made of a plastic material with conductive material or a metal material with higher strength.

[0098] Furthermore, the pusher 562 is constructed as a rod extending from the first end of the housing 510 to the second end of the housing. The pusher 562 may also be composed of multiple rod segments, which will not be elaborated here. The pusher 562 includes a forced pushing portion 562a and an electrical contact portion 562b. In the first direction, the forced pushing portion 562a is disposed at the first end of the pusher 562, and the electrical contact portion 562b is disposed at the second end of the pusher 562. Specifically, the forced pushing portion 562a can contact the forced pushing slope 541a of the forced pushing protrusion 541 of the force receiving member 540 and can be forced to push the forced pushing slope 541a, so that the pusher 562 moves in the first direction from the first end of the housing 510 toward the direction close to the second end of the housing 510, so that the pusher 562 moves in the direction close to the second end of the housing 510. Figure 8 The disengagement position shown has been moved to Figure 9 The contact position, when the pusher 562 is located Figure 8 When the contact position is removed, the electrical contact portion 562b is separated from the conductive element 563 (described below) by a distance; when the pusher 562 is in the contact position, the electrical contact portion 562b remains in contact with the conductive element 563.

[0099] The processing box 500 also includes a conductive element 563. In the first direction, the conductive element 562 is located at the second end of the housing 510. One end of the conductive element 562 can contact the electrical contact portion 562b, and the other end can contact the first grounding surface of the first grounding element 553. That is, the conductive element 563 can serve as an intermediate electrical connector to electrically connect the pushing element 562 and the first grounding element 553, so as to realize the grounding and non-grounding of the developing roller 501 and the powder feeding roller. Furthermore, the conductive element 563 can be made of plastic material or metal material preferred in this embodiment to improve the strength and electrical stability of the conductive element 563.

[0100] Furthermore, the processing box 500 also includes a second bearing portion 567 disposed at the second end of the housing 510, which can not only support the second end of the pusher 562, but also rotatably support the developing roller 501 and the powder feeding roller. Furthermore, the second bearing portion 567 is supported by a conductive material.

[0101] When the pusher 562 is located as Figure 9When the pusher is in the contact position shown, the electrical contact portion 562b contacts the conductive element 563, thus maintaining an electrical connection between the pusher 562 and the first grounding element 553, achieving the grounding effect of the pusher 562. Furthermore, since the pusher 562 is supported on the conductive second bearing portion 567, which also rotatably supports the developing roller 501 and the powder feeding roller, the developing roller 501 and the powder feeding roller achieve an electrical connection with the first grounding element 553, thereby achieving the grounding effect of the developing roller 501 and the powder feeding roller. When the pusher 562 is in the discontinuation position, the electrical contact portion 562b is discontinuing contact with the conductive element 562 and separated by a distance, preventing the first grounding element 553 from being electrically connected to the pusher 562 through the conductive element 562. Therefore, the grounding effect of the developing roller 501 and the powder feeding roller cannot be achieved at this time. In this case, the developing roller 501 and the powder feeding roller can normally receive power from the first electrode 568 located at the second end of the housing 510, achieving normal printing.

[0102] Furthermore, the processing box 500 also includes a first elastic member 564 disposed at the second end of the pusher 562. The first elastic member 564 is preferably a compression spring. The elastic force generated by the compression of the first elastic member 564 can be applied to the pusher 562, and can be used to reset the pusher 562 after it has moved, so that the pusher 562 can move from the contact position to the disengagement position.

[0103] The following will describe in detail the cooperative operation process between the force receiving component 540 and the control component in this embodiment, so as to achieve the technical effect of controlling the grounding or non-grounding of the developing roller 501 and the powder feeding roller.

[0104] When the processing cartridge 500 performs a print job, such as Figure 4 , Figure 5 , Figure 8 As shown, the developing roller 501 remains in contact with the photosensitive drum 502. At this time, the force receiving member 540 is in the first position, and the pushing member 562 is in the disengaged position, that is, the electrical contact portion 562b is disengaged from the conductive member 563, and the developing roller 501 and the powder feeding roller are not grounded. When the processing cartridge 500 does not need to perform a printing task, the first force receiving portion 540b1 of the force receiving member 540 is pushed by the pushing portion of the pushing assembly of the imaging device, causing the force receiving member 540 to move from the first position. Figure 4 , Figure 5 , Figure 8 The first position shown is as follows Figure 6 , Figure 7 , Figure 9As shown in the second position rotation, during the rotation of the force receiving member 540, the pushing slope 541a of the pushing protrusion 541 pushes the pushing portion 562a of the pushing member 562, causing the pushing member 562 to overcome the elastic force of the first elastic member 564 and move from the disengaged contact position to the contact position in the first direction. The pushing member 562 makes contact with the conductive member 563 through the electrical contact portion 562b, realizing the electrical connection with the first grounding member 553. Since the conductive second bearing portion 567 simultaneously supports the developing roller 501, the powder feeding roller, and... The pusher 562 enables the developing roller 501 and the powder feeding roller to be electrically connected to the pusher 562, thus achieving the grounding effect of the developing roller 501 and the powder feeding roller, thereby suppressing the transfer of developer. It is worth mentioning that after the force receiving member 562 moves from the first position to the second position, the holding portion 540a of the force receiving member 540 can be used to hold the position of the force receiving member 540, thereby holding the position of the pusher 562 in the first direction, thereby ensuring that the electrical contact portion 562b maintains stable contact with the conductive member 563. When the processing cartridge 500 needs to perform a printing task again, the pushing component of the imaging device can push the second force receiving portion 540b2 of the force receiving member 540, breaking the state in which the holding portion 540a holds the force receiving member 540 in a stable position. The force receiving member 540 moves from the second position to the first position. During the movement of the force receiving member 540, the forced pushing portion 562a of the pushing member 562 loses the support of the forced pushing protrusion 541 of the force receiving member 540. At this time, the elastic force of the first elastic member 564 is released and applied to the pushing member 562, causing the pushing member 562 to move from the contact position to the discontinuation contact position in the first direction. That is, at this time, the electrical contact portion 562b and the conductive member 563 are no longer electrically connected, and the pushing member 562 is no longer grounded. This allows the developing roller 501 and the powder feeding roller to normally receive the power of the first electrode 568, so that the processing cartridge 500 can normally perform the printing task.

[0105] Example 2

[0106] like Figure 10-12 As shown, the following will introduce Embodiment 2 of the present invention. Embodiment 2 shows a processing box 800. The processing box 800 is the same as the processing box 800 of Embodiment 1 above, which will not be repeated here. The difference is that the structure for connecting the developing roller to electricity and grounding or not grounding is different.

[0107] In the processing box 800, to simplify the structure, no pushing components or other parts are provided. Specifically, the processing box 800 also includes a second grounding member 850 disposed at the first end of the housing, which is preferably made of conductive metal. The second grounding member 850 is supported and mounted on the force receiving member 840, which allows the second grounding member 850 to move between a first position and a second position in response to the rotation of the force receiving member 840. The second grounding member 850 includes a first contact portion 851 and a second contact portion 852 located at its two ends, respectively. When the processing box 800 needs to perform a printing task, i.e., when the force receiving member 840 is in the first position, the second grounding member 850... The contact portion 852 contacts the grounding portion at the first end of the imaging device. The grounding portion of the imaging device (also known as a conductive component) can be the metal part of the cartridge frame or other components in the imaging device, as long as it can achieve the technical effect of grounding. However, at this time, the first contact portion 851 is disengaged from the first bearing portion 860, which is a rotatable support for the developing roller 808 and the powder feeding roller located at the first end of the housing and is conductive. This makes it impossible for the first bearing portion 860 and the developing roller 608 and the powder feeding roller supported on the first bearing portion 860 to be grounded. Therefore, the developing roller 808 and the powder feeding roller can perform printing normally.

[0108] When the processing cartridge 800 does not need to perform a printing task, i.e., when the force receiver 840 is in the second position, the second contact portion 852 is still in contact with the grounding portion of the imaging device, and the first contact portion 851 remains in contact with the first bearing portion 860. This allows the first bearing portion 860, as well as the developing roller 808 and the powder feeding roller supported on the first bearing portion 860, to be grounded, thus preventing the developer from being delivered from the developing roller 808 to the photosensitive drum 802.

[0109] Furthermore, to ensure that the second contact portion 852 maintains stable contact with the grounding portion of the imaging device, preferably, a portion of the second grounding member 850 near the second contact portion 852 can undergo elastic deformation.

[0110] Therefore, by placing the second grounding member 850 at the first end of the housing, the processing box 800 of this embodiment achieves a similar technical effect to the technical solution in Embodiment 1 above, while further simplifying the structure of the processing box 800 and reducing production costs.

[0111] Example 3

[0112] like Figure 13-18 As shown, Embodiment 3 of the present invention is illustrated. Embodiment 3 shows a processing cartridge 500, which is the same as the processing cartridge in Embodiment 1 above, and will not be described again here. The difference is that a new technical solution is provided to suppress the transfer of developer from the developing roller 501 to the photosensitive drum 502.

[0113] The processing cartridge 500 includes a first electrode 568 that is retractable in a first direction to disconnect the electrical connection between the toner roller, the developing roller 501 and the imaging device when the processing cartridge 500 is not performing a printing task. Specifically, the processing cartridge 500 also includes a push member 565 disposed at the second end of the housing. When the push member 562 moves from the first end of the housing toward the second end of the housing in the first direction, the push member 565 can be pushed by the push member 562, so that the push member 562 can move in a direction intersecting the first direction. Preferably, the push member 562 can move at least in the second direction from the fourth end of the housing near the photosensitive drum 502 toward the third end of the housing away from the photosensitive drum 502. Furthermore, at least one of the portions of the push member 565 and the push member 562 that contact each other is constructed as a slope to improve the smoothness of the push.

[0114] Furthermore, the first electrode 568 can pass through a hole 567a provided in the second bearing portion 567, so that the first electrode electrical contact portion 568a of the first electrode 568 is exposed to the outside of the processing box 500, so that the first electrode electrical contact portion 568a can be electrically connected to the power supply component (also known as a conductive component) of the imaging device; specifically, the first electrode 568 includes a connecting portion 568c configured as an elastic buckle, the first electrode 568 is connected to the second bearing portion 567 through the connecting portion 568c, so that the first electrode 568 is movably and detachably mounted on the second bearing portion 567; the second bearing portion 567 also includes a pushed portion 568b, the pushed portion 568b is configured as an inclined surface and can be pushed by the pushed member 565, so that the first electrode 568 can be moved from the first direction as shown in the figure Figure 14 , Figure 16 The extended position shown is moved to the position shown. Figure 15 , Figure 17 The retracted position shown indicates that, compared to the extended position, at least a portion of the first electrode 568 in the retracted position is closer to the first end of the housing. When the first electrode 568 is in the extended position, the first electrode electrical contact portion 568a of the first electrode 568 remains in contact with the power supply component of the imaging device, allowing the developing roller 501 and the powder feeding roller to receive power from the imaging device normally, ensuring normal printing of the processing cartridge. When the first electrode 568 is in the retracted position, the first electrode electrical contact portion 568a of the first electrode 568 is out of contact with the power supply component of the imaging device. At this time, the developing roller 501 and the powder feeding roller cannot receive power from the imaging device, thereby inhibiting the transfer of developer from the developing roller 501 toward the photosensitive drum 502.

[0115] Furthermore, the processing box 500 also includes a second elastic element 569, which is preferably a compression spring and is disposed between the first electrode 568 and the housing, so that when the first electrode 568 is in the retracted position and needs to be reset, the second elastic element 569 can apply an elastic force to the first electrode 568, so that the first electrode 568 can be reset and moved to the extended position, thereby performing normal printing.

[0116] When part of the processing cartridge 500 does not need to perform a printing task, the force receiver 540 moves from the first position to the second position. The pushing protrusion 541 of the force receiver 540 pushes the pusher 562, causing the pusher 562 to move in the first direction. This causes the first electrode 568 to move from the extended position to the retracted position, disconnecting the electrical connection between the developing roller 501, the powder feeding roller and the imaging device. This also prevents the developer of the developing roller 501 from transferring towards the photosensitive drum 502, thus avoiding printing defects.

[0117] Example 4

[0118] like Figure 19-27 As shown, the following will introduce Embodiment 4 of the present invention. Embodiment 4 shows a processing box 1000. The similarities between the processing box 1000 and Embodiments 1-3 above will not be repeated. The difference is that the structure for connecting the developing roller to electricity and grounding or not grounding is different.

[0119] First, such as Figure 19 box Figure 24 As shown, the processing cartridge 1000 also includes a second electrode 1069 and a third electrode 1014 located at the second end of the housing and separately disposed from the first electrode 1068. The first electrode 1068 and the second electrode 1069 are disposed adjacent to each other. Compared with the third electrode 1014, the first electrode 1068 is closer to the second electrode 1069. The first electrode 1068 is used to contact the first power supply component of the imaging device and be electrically connected to at least one of the developing roller 1001, the powder feeding roller (not shown), and the powder discharging blade (not shown). The second electrode 1069 is used to contact the second power supply component of the imaging device and be electrically connected to the charging roller 1003. The third electrode 1014 is used to contact the third power supply component of the imaging device and is also electrically connected to the charging roller 1003. The specific structures of the first electrode 1068, the second electrode 1069, and the third electrode 1014, as well as the structure of the processing cartridge 1000 that cooperates with them, will be described in detail below.

[0120] like Figure 24As shown, the first electrode 1068 includes a first electrode contact portion 1068a and a first electrode connection portion 1068b. The first electrode contact portion 1068a can contact the first power supply component of the imaging device to receive power from the first power supply component. The processing box 1000 is still provided with an electrical transmission member 1062 extending from the second end of the housing to the first end of the housing in a first direction. The electrical transmission member 1062 is mounted on the first housing and is constructed as a rod made of conductive material. The electrical transmission member connection portion 1062a of the electrical transmission member 1062 located at the second end of the housing is in contact with the first electrode electrical connection portion 1068b of the first electrode 1068. That is, the first electrode 968 is in contact with the first electrode contact portion 1068b of the first electrode 1068. The power received in the device can be transmitted to the power transmission component 1062; the power transmission component 1062 also includes a power transmission component contact portion 1062b located at the first end of the housing, the power transmission component contact portion 1062b maintaining contact with the force receiver 1040, the force receiver 1040 also being made of conductive material, so the power transmission component 1062 can further transmit power to the force receiver 1040; when the force receiver 1040 is in the first position, the force receiver contact portion 1040a of the force receiver 1040 maintains an electrical connection with the developing roller shaft 1001a of the developing roller 1001 at the first end of the housing, so that the force receiver 1040 can transmit power to the developing roller 1001.

[0121] like Figure 24-25As shown, the processing cartridge 1000 also includes a first bearing portion 1067 located at the first end of the housing. The first bearing portion 1067 is also made of conductive material. The first bearing portion 1067 not only rotatably supports the developing roller shaft 1001a and the powder feeding roller shaft, allowing the power transmitted to the developing roller 1001a to be transmitted to the powder feeding roller via the first bearing portion 1067, but also allows the power on the first bearing portion 1067 to be operably transmitted to the powder dispensing blade. That is, when the force receiver 1040 is in the first position, the power received by the first electrode 1068 from the first power supply component of the imaging device can be sequentially transmitted through the electric transmission component 1062 and the force receiver 1040 to the developing roller 1001a, the powder feeding roller, and the powder dispensing blade 1007. Optionally, the force receiver 1040 and the first bearing portion 1067 can be... The structure is made of non-conductive material, and the electricity can be transmitted through the transmission member 1062 and then directly to the developing roller 1001, the powder feeding roller, and the powder dispensing blade 1007 through other conductive components. However, at least a part of the conductive component can move in response to the movement of the force receiving member 1040. When the force receiving member 1040 moves from the first position to the second position, that is, when the processing cartridge 1000 does not need to perform a printing task, the force receiving member contact portion 1040a of the force receiving member 1040 disengages from the developing roller shaft 1001a of the developing roller 1001. This prevents the electricity received by the first electrode 1068 from the first power supply component of the imaging device from being transmitted to the developing roller shaft 1001a, and thus cannot be transmitted to the developing roller 1001, the powder feeding roller 1005, and the powder dispensing blade 1007. This can suppress the transfer of developer adhering to the developing layer of the developing roller 1001 to the photosensitive drum 1002. Alternatively, in this embodiment, the developing roller shaft 1001a of the developing roller 1001 can be made of non-metallic material or insulating material, or the outer surface of the developing roller shaft 1001a can be coated with insulating material, and the developer carrier layer covering the outer surface of the developing roller shaft 1001a can be made of conductive material, so that the power of the first electrode 1068 cannot be transmitted to the developer carrier layer through the developing roller shaft 1001a, but the powder dispensing knife 1007 can transmit the power to the developer carrier layer through contact with the developer carrier layer, thereby simplifying the power transmission structure. Therefore, to achieve the above technical effect, the force receiving member 1040 is configured to disconnect the electrical connection between the powder dispensing knife 1007 and the first electrode 1068 by moving from the first position to the second position, thereby indirectly disconnecting the electrical connection between the imaging device and the developing roller 1001.

[0122] Furthermore, to further improve print quality, the processing cartridge 1000 also includes a first diode 1072. In a first direction, the first diode 1072 is arranged at the second end of the housing. The first connection portion 1072a (i.e., the positive electrode portion of the first diode 1072a) of the first diode 1072 is connected to the second end of the developing roller shaft 1001a, and the second connection portion 1072b (i.e., the negative electrode portion of the first diode 1072a) of the first diode 1072 is connected to the ground portion of the imaging device. When the processing cartridge 1000 is not performing printing work, even if the developing roller 1001 can no longer receive the power supplied by the first electrode 1068, the developer adhering to the developing roller 1001 itself may have residual positive charge due to friction, or the power from the imaging device may be transferred through the photosensitive drum 1002. If the charged developer on the developing roller 1001 participates in development normally, the print quality will be reduced, resulting in defects such as background gray. However, since the processing cartridge 1000 is equipped with a first diode 1072, the positive charge of the developer attached to the developing roller 1001 can be conducted to the grounding part of the imaging device through the first diode 1072. Then, through the potential difference between the developing roller 1001 and the photosensitive drum 1002, the tendency of the developer on the developing roller 1001 to transfer to the photosensitive drum 1002 is suppressed. This helps to improve the print quality of the processing cartridge 1000. However, it is worth mentioning that in this embodiment, the first diode is mainly used to further improve the print quality and is not a necessary structure. That is to say, the first diode can also be omitted.

[0123] Furthermore, as described above, the developing roller 1001 of the processing cartridge 1000 is in continuous contact with the photosensitive drum, and the third electrode 1014 of the processing cartridge 1000, which contains color developer and does not participate in development, cannot continuously receive power from the third power supply component of the imaging device. Specifically, when the processing cartridge 1000 does not need to participate in development, the third power supply component only supplies power to the processing cartridge 1000 for a few seconds to ensure that the photosensitive drum 1002 is completely separated from the developing roller 1001 before development. Electrode 02 will still be charged, creating a potential difference with the developing roller 1001 to inhibit developer transfer. After a period of separation between the developing roller 1001 and the photosensitive drum 1002, the power will be cut off. In other words, the power on the third electrode 1014 is not continuous. Because the photosensitive drum 1002 can no longer receive voltage from the imaging device, a small amount of color developer may transfer to the photosensitive drum 1002 through friction between the developing roller 1001 and the photosensitive drum 1002, causing the photosensitive drum 1002 to transfer the color developer onto the developing roller. On the paper, printing color mixing defects occur. Therefore, to further suppress the transfer of developer on the developing roller 1001 to the photosensitive drum 1002 through friction, it is necessary to ensure that a certain potential difference exists continuously between the developing roller 1001 and the photosensitive drum 1002, thereby suppressing the transfer of color developer. To this end, this embodiment provides an implementation method, namely, the charging roller 1003 can rely on the first electrode 1068 or the second electrode 1069 (regardless of whether the processing cartridge 1000 containing color developer participates in development, the first... Both electrode 1068 and the second electrode 1069 will remain continuously energized due to the power supplied. It should be noted that the processing box 1000 operates at a negative voltage. Since the absolute value of the voltage of the second electrode 1069 is greater than the absolute value of the voltage of the first electrode 1068, in order to ensure that the voltage of the charging roller 1003 is high enough so that the photosensitive drum 1002 is charged and forms a sufficiently large potential difference with the developing roller 1001, this embodiment preferably supplies power to the charging roller 1001 through the second electrode 1069.

[0124] Furthermore, such as Figure 24-25As shown, the second electrode 1069 of the processing cartridge 1000 includes not only a second electrode contact portion 1069a that can contact the second power supply component of the imaging device, but also a second electrode connection portion 1069b that can contact the third electrode 1014. The second electrode contact portion 1069a and the second electrode connection portion 1069b are electrically connected through the middle portion 1069c of the second electrode. With this arrangement, the power received by the second electrode 1069 from the second power supply component of the imaging device can also be transferred to the third electrode 1014. When the processing cartridge 1000 is performing a printing task normally, the power of the second electrode 1069 and the third electrode 1014 can be transmitted through the elastic member 1015 made of conductive material and the charging roller bearing bracket 10. 16 is transferred to the charging roller 1003. When the processing cartridge 1000 is not performing a printing task, since the third electrode 1014 can no longer receive power from the third power supply component of the imaging device after a few seconds, the charging roller 1003 can be charged by the power supplied by the second electrode 1069. This allows the charging roller 1003 to still charge the photosensitive drum 1002, so that the photosensitive drum 1002 can still be charged when the processing cartridge 1000 is not performing a printing task. At this time, since the potential on the developing roller 1001 is greater than the potential on the photosensitive drum 1002, the tendency of the developer to move to the photosensitive drum 1002 through the electric field force is suppressed, and the photosensitive drum 1002 will no longer be contaminated, thereby improving the printing quality of the processing cartridge 1000.

[0125] Alternatively, the power received by the second electrode 1069 may not be transmitted to the charging roller 1003 via the third electrode 1014, but can instead be transmitted to the charging roller 1003 via a separate conductive path. Specifically, for example... Figure 26As shown, in this scheme, an electrical delay element and a second diode are provided between the second electrode 1069 and the charging roller 1003. The negative terminal of the second diode is electrically connected to the electrical delay element, and the positive terminal is electrically connected to the charging roller. The electrical delay element is preferably an inductor, capacitor, or resistor, thereby delaying the time required for the power from the second electrode 1069 to be transferred to the charging roller 1003. A third diode is provided between the third electrode 1014 and the charging roller 1003. The negative terminal of the third diode is electrically connected to the third electrode 1014, and the positive terminal of the third diode is electrically connected to the charging roller 1003. When the processing cartridge performs a color printing task, in the processing cartridge 1000 containing color developer, the power received by the third electrode 1014 from the third power supply component can be transferred to the charging roller 1003 via the third diode to charge the charging roller 1003. The charging roller 1003 then charges the photosensitive drum 1002 to ensure normal development. In the processing cartridge 1000 containing color developer, due to the delay effect of the electrical delay element, the power received by the second electrode 1069 from the second power supply component is transferred to the second diode later than the power transferred from the third electrode 1014 to the third diode. Therefore, the charging roller 1003 receives the power from the third electrode 1014 first, thereby charging the photosensitive drum 1002. Since the potential of the second electrode 1069 is greater than that of the third electrode 1014, under the unidirectional conductivity of the second diode, the voltage of the second electrode 1069 cannot be transferred to the charging roller 1003, which has a lower voltage. This blocks the voltage transfer of the second electrode 1069, so that the charging roller 1003 can only receive the power from the third electrode 1014 at this time, and cannot receive the power from the second electrode 1069, thereby ensuring the power stability of the charging roller 1003.When the imaging device performs a black and white printing task, in the processing cartridge 1000 containing the color developer, as previously described, the power from the third power supply component is only supplied to the third electrode 1014 for a few seconds. During this process, the voltage of the charging roller 1003 is lower than the voltage of the developing roller 1001, thus suppressing the transfer of developer to the photosensitive drum 1002. Furthermore, since the voltage of the charging roller 1003 is still lower than the voltage received by the second electrode 1069 at this time, the voltage of the second electrode 1069 cannot be transmitted to the charging roller 1003 through the second diode during these few seconds. However, when the power from the third power supply component is no longer supplied... When the voltage reaches the third electrode 1014, the voltage of the charging roller 1003 rapidly drops to 0V. At this point, the voltage of the charging roller 1003 is greater than the voltage of the second electrode 1069. Therefore, almost simultaneously, the second diode will no longer block the flow, allowing the voltage of the second electrode 1069 to pass through. This allows the charging roller 1003 to receive the voltage from the second electrode 1069 and become charged again, thus enabling the photosensitive drum 1002 to be continuously charged. Consequently, the voltage on the surface of the photosensitive drum 1002 will always be less than the voltage on the surface of the developing roller 1001. In other words, there is always a potential difference between the two, which inhibits the transfer of developer. It should be noted that regardless of whether black or color is being printed, the processing cartridge containing black developer will always participate in the developing process. That is, there will always be a potential difference between the photosensitive drum 1002 and the developing roller 1001 to inhibit developer transfer. Therefore, the processing cartridge containing black developer does not need to have the aforementioned developer-inhibiting structure, which simplifies the structure of the processing cartridge containing black developer and reduces production costs.

[0126] As can be seen from the above description, the electrical connection or disconnection between the developing roller 1001 and the first electrode 1068 of the imaging device in this embodiment can be switched according to the movement of the force receiving member 1040. It should be noted that the movement of the force receiving member 1040 can also force the developing roller 1001 to be electrically connected or disconnected from the grounding part of the imaging device, as shown in Embodiments 1 or 2 above. Furthermore, since the charging roller 1003 can receive voltage from the second electrode 1069, the developing roller 1001 does not need to be continuously grounded when the processing cartridge 1000 is not performing a task; it can be grounded for a period of time before being disconnected. No longer grounded, that is, when the force receiver 1040 is pushed to a state that grounds the developing roller 1001, after a period of time, the imaging device completes the recognition action. After the pushing force applied to the force receiver 1040 is removed, the force receiver 1040 can be reset again under the action of the reset component (not shown in the figure), so that the developing roller 1001 is no longer grounded. It is precisely because the charging roller 1003 has voltage at this time that the photosensitive drum 1002 still has a lower voltage than the developing roller 1003 when the processing cartridge 1000 is not performing a printing task. The developer on the developing roller 1001 also cannot be transferred to the photosensitive drum 1002.

[0127] Example 5

[0128] like Figure 28-36 As shown, a processing cartridge 1000 according to Embodiment 5 of the present invention is illustrated. The similarities with Embodiment 4 above will not be repeated here. The difference is that the processing cartridge 1000 also includes a voltage regulation device to further suppress developer transfer in order to improve print quality.

[0129] It is important to understand that when the processing cartridge 1000 containing color developer performs a printing task, the third electrode 1014 charges the photosensitive drum 1002 via the charging roller 1003. The potential difference between the developing roller 1001 and the photosensitive drum 1002 is large enough to ensure that the developer is transferred onto the photosensitive drum 1002. However, since the absolute value of the voltage of the second electrode 1069 is much smaller than the absolute value of the voltage of the third electrode 1014, when the processing cartridge 1000 containing color developer does not perform a printing task... During operation, the second electrode 1069 charges the photosensitive drum 1002 via the charging roller 1003. At this time, the voltage difference between the photosensitive drum 1002 and the developing roller 1001 is small. This may cause some developer on the developing roller 1001 to still transfer to the photosensitive drum 1002, thus contaminating the photosensitive drum 1002 and reducing print quality. Therefore, to further improve the print quality of the processing cartridge 1000, the difference lies in that the processing cartridge 1000 also includes a voltage regulating device 1009, such as... Figure 28As shown, in the power transmission direction of the second electrode 1069, a voltage regulating device 1009 is disposed between the second electrode contact portion 1069a and the charging roller 1003. Specifically, the voltage regulating device 1009 can be disposed as follows: Figure 28 The second end of the housing shown can also be located at the first end of the housing. That is, the voltage output from the second electrical contact portion 1069a does not need to be electrically connected to the charging roller 1003 at the second end of the housing, but can be transmitted via the electrical transmission element 1062 and then electrically connected to the charging roller 1003 at the first end of the housing. This is not a limitation. Specifically, the voltage adjustment device 1009 can increase the absolute value of the voltage received by the second electrode 1069 from the imaging device, thereby increasing the absolute value of the voltage received by the charging roller 1003. Ultimately, the absolute value of the voltage of the photosensitive drum 1002 can also be increased accordingly. This increases the voltage difference between the photosensitive drum 1002 and the developing roller 1001, which can further suppress the transfer of developer on the developing roller 1001 to the photosensitive drum 1002, improving printing quality. Quality; however, the absolute value of the voltage increased by the voltage regulating device 1009 should not be too high. If it exceeds the absolute value of the voltage received by the third electrode 1014 by too much, it will easily have an adverse effect on the performance of the photosensitive drum 1002 when the charging roller 1003 charges the photosensitive drum 1002, thereby affecting the electrostatic latent image of the photosensitive drum 1002. This will undoubtedly be counterproductive and reduce the printing quality of the processing cartridge 1000. Therefore, the voltage increased by the voltage regulating device 1009 should be appropriate. The absolute value of the voltage increased by the voltage regulating device is defined as P, 50V < P < 3000V, preferably 50V < P < 1000V. Within this range, the processing cartridge has a better printing effect when the processing cartridge 1000 is not performing a printing task; more preferably, 350V < P < 700V.

[0130] More specifically, such as Figures 31-36As shown, the voltage regulating device 1009 includes a power supply component 1091 and a regulating component 1092. Preferably, the power supply component 1091 and the regulating component 1092 are supported in a receiving cavity 1010a1 at the upper end of the first housing 1010a. Both can be at least partially covered by a cover component 1008 detachably mounted on the first housing 1010a to protect the power supply component 1091 and the regulating component 1092 from damage. Alternatively, the power supply component 1091 and the regulating component 1092 can also be installed in the second housing 1010b, or one of them can be installed in the first housing 1010a and the other in the second housing 1010b; this is not limited. The power supply component 1091 can use a power supply component with energy storage function, such as a battery, to power the regulating component 1092, or it can use a generator component to power the regulating component 1092. 2. Power supply: In a preferred embodiment of this invention, the power supply component 1091 is a generator. The generator can convert mechanical energy into electrical energy and supply the electrical energy to the regulating component 1092. The source of mechanical energy can be a rotatable component in the processing box 1000, such as: a first coupling component 1020 that can receive the rotational driving force of the imaging device, the developing roller 1001, the powder feeding roller, or a developing roller gear disposed at one end of the developing roller 1001, or a powder feeding roller gear disposed at one end of the powder feeding roller. It can also be a charging roller 1003, a photosensitive drum 1002, or a second coupling component 1021 used to drive the photosensitive drum to rotate. This is not a limitation. However, as a preferred embodiment, the generator component 1091 is configured to receive the driving force of the first coupling component 1020 used to drive the developing roller 1001 to rotate and convert mechanical energy into electrical energy.

[0131] Specifically, the first end of the first housing 1010a of the processing box 1000 is provided with a first coupling component 1020, a first transmission gear 1021, a second transmission gear 1022, and a third transmission gear 1023. The first transmission gear 1021 is coaxially arranged with the first coupling component 1020 and can rotate by receiving the driving force of the first coupling component 1020. The third transmission gear 1023 is connected to the drive shaft 1091a of the power generation component 1091. The second transmission gear 1022 meshes between the first transmission gear 1021 and the third transmission gear 1023. The first coupling component... The driving force received by 1020 from the imaging device can be transmitted sequentially via the first transmission gear 1021, the second transmission gear 1022, and the third transmission gear 1023, and finally the third transmission gear 1023 drives the drive shaft 1091a of the power generation component 1091 to rotate. The power generation component 1091 then generates electrical energy through the operation of its internal stator, rotor, and other components, which can then supply power to the adjustment component 1092. It is worth mentioning that the number of transmission gears in this embodiment is not limited, and can be the three mentioned in the above embodiment, or one to two or more.

[0132] like Figure 30 As shown, the adjustment component 1092 includes components such as an inductor, a winding coil, and an output capacitor. It is used to boost the absolute value of the initial voltage output by the power supply component 1091. After the voltage is boosted by the adjustment component 1092, the voltage reaches a predetermined value. By electrically connecting the negative terminal of the adjustment component 1092 to the charging roller 1003 and electrically connecting the positive terminal of the adjustment component 1092 to the ground, the adjustment component 1092 can output negative electricity to the charging roller 1003, thereby achieving a stable charging effect for the photosensitive drum 1002.

[0133] When the imaging device performs high-quality color printing, the printing time for a single page is relatively long. During this time, the rotation speed of the driving head of the imaging device is relatively slow, which in turn leads to a slower rotation speed of the drive shaft 1091a of the power generation component 1091. This results in a lower absolute value of the output voltage of the power generation component 1091, and the boost component 1092 is unable to raise the absolute value of the voltage to the predetermined value, leading to a decrease in print quality. Therefore, to avoid this problem and further improve print quality, one approach is to preset the absolute value of the output voltage of the voltage regulating device 1009 to 600-1500V. This ensures that even when the rotation speed of the first coupling component 1020 is slow, the electricity generated by the power generation component 1091 can still enable the voltage regulating device 1009 to reach the predetermined value, thus providing normal power to the charging roller 1003. When the rotation speed of the first coupling component 1020 is normal, the electricity generated by the power generation component 1091 will not cause the absolute value of the output voltage of the voltage regulating device 1009 to be too high, avoiding the risk of the photosensitive drum 1002 being damaged by excessive voltage.

[0134] This solution also provides another implementation method, as follows: Figure 29As shown, based on the processing box 1000 using the voltage adjustment device 1009 described above, this embodiment retains the third electrode 1014. A third diode is connected between the third electrode 1014 and the charging roller 1003, wherein the negative terminal of the third diode is electrically connected to the third electrode 1014, and the positive terminal of the third diode is electrically connected to the charging roller 1003; furthermore, an electrical delay element and a fourth diode are also provided between the adjustment component 1092 and the charging roller 1003, wherein the negative terminal of the fourth diode is electrically connected to the electrical delay element, and the positive terminal of the fourth diode is electrically connected to the charging roller 1003; when the imaging device performs a high-quality color page printing task, the imaging device can normally supply... The voltage is supplied to the third electrode 1014, and then to the charging roller 1003 via the third diode, thereby charging the photosensitive drum 1002 and achieving the technical effect of suppressing the transfer of developer from the developing roller 1001 to the photosensitive drum 1002. It should be noted that after the power generation component 1091 generates electricity, it first supplies the voltage to the voltage regulating device 1009. After regulation by the voltage regulating device 1009, its output voltage is first delayed by an electrical delay element before proceeding to the next step. Since the conductive path from the third electrode 1014 to the charging roller 1003 does not have this electrical delay element, it reaches the charging roller 1003 first and charges it. This is because, during high-quality color printing... During printing, the rotation speed of the drive head in the color processing cartridge 1000 is relatively slow, and the voltage regulating device 1009 cannot output the predetermined voltage value. That is, the absolute value of the voltage output by the regulating component is less than the absolute value of the voltage received by the third electrode 1014 from the imaging device. However, since both are negative voltages, the voltage output by the regulating component is greater than the voltage received by the third electrode 1014 from the imaging device. In other words, the voltage on the charging roller 1003 is less than the voltage at the negative terminal of the fourth diode. Due to the unidirectional conductivity of the fourth diode, the voltage output by the voltage regulating device 1009 is blocked by the fourth diode and cannot be transmitted to the charging roller 1003. In other words, when imaging... When the device performs high-quality color printing, the charging roller 1003 can be powered only by the third electrode 1014 and not by the voltage regulator 1009, thus avoiding problems such as short circuits. Alternatively, the electrical delay element can be placed between the third electrode 1014 and the third diode instead of the regulator 1092 and the fourth diode, achieving the same technical effect. When the imaging device performs black printing, it is still powered by the voltage regulator 1009 as described in the above embodiment, and will not be repeated here. Furthermore, to simplify the structure and facilitate installation, the electrical delay element and the fourth diode can be installed or integrated into the voltage regulator 1009.

[0135] Example 6

[0136] like Figure 37-42As shown, Embodiment 6 of this embodiment is illustrated. The similarities with the processing box in the above embodiments will not be repeated below. The difference is that when the processing box 1000 performs a black and white page printing task, the power of the charging roller 1003 of the processing box 1000 with color developer comes from another processing box.

[0137] When the operator prints only black and white pages, only the processing cartridge 1000K (hereinafter referred to as the black processing cartridge) containing black developer participates in the printing process, while the processing cartridge 1000 (hereinafter referred to as the color processing cartridge) containing color developer does not participate in the development process. The third electrode 1014 on the black processing cartridge 1000K can receive power from the printer, thus energizing the charging roller 1003 on it. However, since the developing roller 1001 and the photosensitive drum 1002 in this embodiment remain in contact after the processing cartridge 1000 is installed in the imaging device, the third electrode 1014 on the color processing cartridge 1000 cannot continuously receive power from the imaging device because the color processing cartridge 1000 is not working. Consequently, the charging roller 1014 cannot be continuously energized, and therefore cannot charge the photosensitive drum 1002. Since the developing roller 1001 is also not charged or has a negative voltage, the developer can be transferred between the developing roller 1001 and the photosensitive drum 1002 through friction or potential difference, thus contaminating the photosensitive drum 1002 of the color processing cartridge 1000. As a result, during the transfer process, the paper that was originally only printing black pages will have color developer attached to it, thus contaminating the paper. Therefore, to avoid this situation, a modified embodiment of this invention can transfer the power from the third electrode 1014 on the black processing cartridge 1000K to the third electrode 1014 on the color processing cartridge 1000, so that when the color processing cartridge 1000 is not involved in printing, the charging roller 1003 also has power, thereby creating a potential difference between the developing roller 1001 and the photosensitive drum 1002 and suppressing the transfer of developer.

[0138] Specifically, the color processing cartridge 1000 and / or the black processing cartridge 1000K include power transmission components, which include a first power transmission component 1081, a second power transmission component 1014, and a third power transmission component 1082. In this embodiment, the second power transmission component 1014 is the third electrode 1014. In the first direction, the first power transmission component 1081, the second power transmission component 1014, and the third power transmission component 1082 are disposed at the second end of the housing. In the second direction (i.e., the vertical direction), compared to the fourth end of the housing (the end closer to the photosensitive drum 1002), the first... A power delivery component 1081, a second power delivery component 1014, and a third power delivery component 1082 are located closer to the third end (the end closer to the chip's electrical contact surface). In the third direction, the first power delivery component 1081, the second power delivery component 1014, and the third power delivery component 1082 are arranged sequentially and can maintain electrical connection. More specifically, in the third direction of the processing box mounting direction, at least a portion of the first power delivery component 1081 is located upstream of the second power delivery component 1014, and at least a portion of the second power delivery component 1014 is located upstream of the third power delivery component 1082.

[0139] The first power transmission component 1081 has a fifth end facing the housing (i.e., the direction in which the processing cartridge is supported in the tray 2 and detached from the imaging device) and a third power transmission component 1082 has a sixth end facing the housing (i.e., the direction in which the processing cartridge is supported in the tray 2 and installed in the imaging device). When both the black processing cartridge 1000K and the color processing cartridge 1000 are installed in the tray 2 and the imaging device, the third electrode 1014 does not... It can transmit power not only to the charging roller 1003, but also to the third power transmission member 1082 in contact with it. Subsequently, the electrical contact surface 1082 of the third power transmission member of the black processing box 1000K can contact the electrical contact surface 1081a of the first power transmission member of the color processing box 1000 located in front of it, and can receive the power transmitted by the black processing box 1000K. That is to say, the power can be transmitted sequentially through the imaging device, the third electrode 1014, the third power transmission member 1082, and the first power transmission member 1081 of the color processing box 1000.

[0140] Typically, in the installation direction of the processing cartridges, the black processing cartridge 1000K is located at the upstream of the tray 2, meaning that the color processing cartridges 1000 are all located downstream of the black processing cartridge 1000K. Therefore, by providing the power transmission component in each of the color processing cartridges 1000, power can also be transferred between the three color processing cartridges 1000. In other words, the power received by the second power transmission component 1014 of the black processing cartridge 1000K can be sequentially transferred to the three color processing cartridges 1000, ensuring that the charging roller 1003 of the color processing cartridge 1000 is also energized when printing only black and white pages. This prevents the developer on the developing roller 1001 in the color processing cartridge 1000 from being delivered to the photosensitive drum 1002, thus ensuring print quality.

[0141] Furthermore, the first power transmission component 1081, the second power transmission component 1014, and the third power transmission component 1082 are all made of conductive metal materials to provide reliable electrical connection stability and wear resistance. Of course, they are not limited to metal and can also be made of conductive plastic or other materials. Preferably, the third power transmission component 1082 is constructed to be elastic, preferably a spring, so that it has reliable elastic deformation characteristics, thereby maintaining reliable electrical connection stability with adjacent processing boxes. This avoids the problem that the electrical contact surface 1082a of the third power transmission component protrudes too much in the third direction and interferes with the adjacent processing box, or that the electrical contact surface 1082a of the third power transmission component protrudes too little in the third direction and cannot contact the electrical contact surface 1082a of the first power transmission component of the adjacent processing box. The main body of the spring is installed in the mounting hole provided in the second cover 1012 to prevent the spring from shaking and improve the installation stability of the spring.

[0142] Of course, in the installation direction of the processing box 1000, the color processing box 1000 located at the downstream end of the tray 2 is the last processing box for power transmission, so there is no need to set up a third power transmission component 1082. The black processing box 1000K located at the upstream end of the tray 2 is the starting end for power transmission. Since it can receive power from the imaging device by relying on the second power transmission component 1014, there is no need to set up a first power transmission component 1081. Therefore, with the above-described structure, the manufacturing cost of a set of processing boxes can be reduced.

[0143] In summary, in the processing boxes provided in Examples 4-6, one or more circuit transmission paths are added to electrically connect with the charging roller 1003, thereby continuously keeping the charging roller charged and suppressing developer transfer. Regardless of the implementation method, the developer transfer is suppressed by forming a sufficient potential difference with the developing roller 1001. It should be noted that this embodiment only lists a few preferred implementation methods. Other methods of suppressing developer transfer based on this principle will not be described here and are not limited thereto.

[0144] Example 7

[0145] Next, we will combine the appendix Figure 43 This invention will now be described in detail in Embodiment 7. Embodiment 7 shows a processing cartridge 1100. To suppress the transfer of developer from the developing roller 1101 to the photosensitive drum, Embodiment 6 disclosed a scheme that can transmit power from the second power delivery member on the black processing cartridge to the charging roller of the color processing cartridge. However, the scheme adopted in this embodiment is different. Simply put, this embodiment 7 can significantly reduce the amount of color developer on the paper by changing the rotation speed of the developing roller 1101 of the processing cartridge 1100, thereby improving the printing quality. That is, the gear system of the first unit is different. As for the parts of the processing cartridge 1100 that are the same as those in the above embodiments, this embodiment 7 will not be described again.

[0146] Specifically, the first coupling component 1120 of the processing cartridge 1100 includes a first coupling component gear tooth 1120a, and the developing roller gear 1121 has a developing roller gear tooth 1121a. The first coupling component gear tooth 1120a meshes with the developing roller gear tooth 1121a, so that the first coupling component 1120 can drive the developing roller gear 1121 to rotate after receiving the driving force of the imaging device. In turn, the developing roller gear 1121 can drive the developing roller 1101 to rotate. In this embodiment, while keeping the outer diameter of the developing roller 1101 constant, the rotational speed of the developing roller 1101 can be reduced by lowering the speed of the developing roller gear 1121. The rotational speed is used to achieve this effect. To achieve this, the number of teeth Z1 of the first coupling component gear 1120a can be reduced and / or the number of teeth Z2 of the developing roller gear 1121a can be increased. Define P = Z1 / Z2. Preferably, 0.8 < P < 2.2; more preferably, 1.3 < P < 1.7. Within this range, the rotational speed of the developing roller gear 1121 is suitable. It will not be too small, resulting in an excessively slow rotational speed of the developing roller 1101, causing insufficient developing agent delivered to the photosensitive drum and resulting in unclear or missing text. Nor will it be too fast, causing the reduction in the rotational speed of the developing roller 1101 to be insignificant and failing to achieve the desired effect. Preferably, 17 < Z2 < 28; more preferably, 20 < Z2 < 24.

[0147] It is worth mentioning that the solution disclosed in Embodiment 7 can be combined with any of the processing boxes in Embodiments 1-6, or can be independent of any of the processing boxes in Embodiments 1-6.

[0148] Example 8

[0149] Next, we will combine the appendix Figure 44-49 The present invention will now be described in detail in Embodiment 8. Embodiment 8 shows a processing box 1200. The parts of the processing box 1200 that are the same as those in the above embodiments will not be described again. The difference is that when the imaging device performs the drum roller separation action (in this embodiment, the developing roller of the processing box 1200 and the photosensitive drum 1202 will not separate and will always remain in the drum roller contact position), the photosensitive drum 1202 will stop rotating, thereby inhibiting the developer of the photosensitive drum 1202 from being transferred to the transfer belt of the imaging device.

[0150] Specifically, the processing box 1200 is provided with a clutch mechanism located at the first end of the photosensitive drum 1202 in the first direction. The clutch mechanism includes, but is not limited to, a force receiving member 1240, a pressing member 1241, a pressed member 1242, a driving member 1243, a drum flange 1244, an elastic member 1245, a connecting member 1246, and a locking member 1247. The force receiving member 1240 still includes a first force receiving portion 1240b1 and a second force receiving portion 1240b2, which will not be described in detail here. However, the force receiving member 1240 also includes a pushing portion 1240b3. In the second direction, the first force receiving portion 1240b1, the second force receiving portion 1240b2, and the pushing portion 1240b3 are respectively located on both sides of the rotation axis of the force receiving member 1240.

[0151] The pressing member 1241 is generally Y-shaped and constructed as a rod. It is rotatably mounted on the first cover 1211 of the second housing via a connecting shaft 1248 extending in the second direction. This allows the pressing member 1241 to have a degree of freedom of movement in the first direction. The pressing member 1241 includes a force receiving portion 1241b3 and a pressure applying portion 1241b1. The pressure applying portion 1241b1 has a pair to provide a more stable and balanced pressing force. In the third direction, the force receiving portion 1241b3 and the pressure applying portion 1241b1 are located at opposite ends of the swing axis of the pressing member 1241. When the first force receiving portion 1240b1 of the force receiving member 1240 receives the push from the imaging device... When the force is applied, the pushing part 1240b3 can move in a direction intersecting the first direction, so that the pushing force receiving part 1241b3 can receive the pushing force of the pushing part 1240b3. The pressing member 1241 will swing around the connecting shaft 1248, so that at least a part of the pressing force applying part 1241b1 moves in the first direction toward the photosensitive drum 1202. Furthermore, in order to facilitate the pressing member 1241 to be pushed more smoothly, at least one of the pushing force receiving part 1241b3 and the pushing part 1240b3 is provided with an inclined surface, which intersects the rotation direction of the force receiving member 1240. Therefore, through the construction of this inclined surface, the pressing member 1241 can be pushed more smoothly, avoiding jamming due to interference when being pushed.

[0152] The pressed member 1242 is constructed in a disc shape and can receive the pressing force of the pressing member 1241, moving towards the photosensitive drum 1202 in a first direction. In the first direction, the driving member 1243 is closer to the photosensitive drum 1202 than the pressed member 1242, and maintains contact with the pressed member 1242. When the pressed member 1242 moves towards the photosensitive drum 1202 in the first direction, the pressed member 1242 can push the driving member 1243 also towards the photosensitive drum 1202 in the same direction. Directional movement; moreover, the drive member 1243 also includes a drive portion 1243a. When the processing cartridge 1200 is performing a printing task normally, the coupling protrusion 1220a of the first coupling member 1220 can receive the rotational driving force from the imaging device and rotate, so that the drive protrusion 1220b provided on the first coupling member 1220 can drive the drive member 1243 to rotate. That is to say, the drive member 1243 can be pushed to move in the first direction by the pressing member 1242, and can also be driven to rotate by the first coupling member 1220.

[0153] The drum flange 1244 is fixedly connected to the photosensitive drum 1202. The drum flange 1244 has a hollow inner cavity, in which there is a driven portion 1244a. When the processing cartridge 1200 is performing a printing task normally, the driven portion 1244a can contact the driving portion 1243a of the driving component 1243 and be driven to rotate by the driving force 1243, thereby causing the drum flange 1244 to drive the photosensitive drum 1202 to rotate together. However, when the processing cartridge 1200 is not performing a printing task, due to the driving component... The pressed member 1242 pushes the 143 to move toward the photosensitive drum 1202 in the first direction. Therefore, the driving part 1243a of the driving member 1243 will disengage from the driven part 1244a of the drum flange 1244 in the first direction. This will prevent the rotational driving force on the coupling member 1243 from being transmitted to the drum flange, thereby stopping the rotation of the photosensitive drum 1202. This will further suppress the transfer of the developer of the photosensitive drum 1202 to the transfer belt of the imaging device and improve the printing quality.

[0154] The connector 1246 is connected to the inner cavity of the drum flange 1244 via an elastic buckle 1246a structure. The elastic element 1245 is sleeved on the end of the first coupling member 1220 away from the coupling protrusion 1220a in the first direction and is arranged between the connector 1246 and the drive member 1243 in the first direction to provide an elastic restoring force to the drive member 1243, so that the drive member 1243 can be reset to the initial position when it is not subjected to the pressing force of the pressed member 1242 in the first direction, so as to prepare for the next action of the pressed member 1242. Preferably, the elastic element 1245 is a compression spring. The locking member 1247 can be used to lock the first coupling member 1220 on the connector 1246 to prevent the first coupling member 1220 from moving in the first direction and affecting its coupling success rate with the imaging device.

[0155] Example 9

[0156] like Figures 50-52 As shown, the processing box 100 of Embodiment 9 of the present invention will be introduced next. The processing box 100 has the same features as the processing boxes in Embodiments 1-8. For example, the developing roller 103 and the photosensitive drum 104 will always remain in contact when the processing box 100 performs a printing task or not. The above and other similarities will not be repeated in this embodiment. The difference is that the first force receiving part 108 and the second force receiving part 107 are both disposed on the force receiving member 140, similar to those in Embodiment 1. Of course, it is optional that the first force receiving part 108 of the processing box 100 is movably disposed on the first unit 110, and the second force receiving part 107 is disposed on the force receiving member 140, that is, the first force receiving part 108 and the second force receiving part 107 are separately disposed.

[0157] Furthermore, the second force receiving portion 106 includes a connecting portion 107 facing the first force receiving portion 108, at least a portion of the connecting portion 107 being configured to undergo elastic deformation when subjected to force; preferably, the connecting portion 107 is an elastic component such as sponge, foam, rubber, or spring.

[0158] like Figure 50 As shown, during the process of installing the processing box 100 into the imaging device from top to bottom, the engaging portion 107 of the second force receiving portion 106 engages with the pushing portion 41 of the imaging device. Since the engaging portion 107 can undergo elastic deformation, the lower end of the engaging portion 107 can be squeezed by the pushing portion 41 and undergo elastic deformation. At this time, the engaging portion 107 remains in contact with the pushing portion 41 of the imaging device due to elastic deformation.

[0159] When the processing cartridge 100 needs to switch to a state where it does not need to perform a printing task, the pushing part 41 moves in a third direction away from the photosensitive drum 104. Figure 50 The middle position shown is moved to, as Figure 51 In the first pushing position shown, at least a portion of the deformation of the engaging portion 107 is reduced relative to the pushing portion 41 being in the middle position. The pushing portion 41 pushes the first force receiving portion 108, causing the force receiving member 140 to move relative to the first unit 110, thereby disconnecting the electrical connection between the developing roller 101 and the imaging device. Subsequently, the pushing portion 41 moves from the imaging device under the control of the imaging device. Figure 51 The first push position shown is reset and moved to Figure 50 In the intermediate position shown, the pushing part 41 of the imaging device disengages from the first force receiving part 108 and contacts the engaging part 107 of the second force receiving part 106. At this time, the force receiving member 140 will remain in a position where the electrical connection between the developing roller 101 and the imaging device can be disconnected. Even if the pushing part 41 of the imaging device no longer continuously pushes the first force receiving part 108, the force receiving member 140 can still remain in a position where the electrical connection between the developing roller 101 and the imaging device is continuously disconnected, thereby improving the print quality.

[0160] When the processing cartridge 100 needs to switch from a non-printing state to a state that performs a printing task, the pushing part 41 moves along a third direction toward the photosensitive drum 104. Figure 51 The middle position shown is moved to, as Figure 52In the second pushing position shown, during the movement of the pushing component 41 of the imaging device, the pushing component 41 can press the engaging portion 107 of the second force receiving portion 106 in a third direction toward the photosensitive drum 104. At this time, compared to the pushing component 41 in the middle position, the elastic deformation of the engaging portion 107 is further greater. Then, the pushing component 41 of the imaging device can push the second force receiving portion 106 to move the force receiving member 140 from a first position that disconnects the electrical connection between the developing roller 101 and the imaging device to a second position that maintains the electrical connection between the developing roller 101 and the imaging device. Subsequently, the pushing component 41, under the control of the imaging device, moves from... Figure 52 The second push position shown is reset and moved to Figure 50 The middle position shown is at this point.

[0161] The pushing part 41 of the imaging device will still remain in contact with the engaging part 107 of the second force receiving part 106, and as described above, the pushing part 41 will disengage from the first force receiving part 108. At this time, the force receiving member 140 will remain in a position where the developing roller 101 is electrically connected to the imaging device. Even if the pushing part 41 of the imaging device no longer continuously pushes the second force receiving part 106, the force receiving member 140 can remain in a position where the electrical connection between the developing roller 101 and the imaging device is continuously disconnected, thereby ensuring normal printing of the processing cartridge 100.

[0162] In general, in this embodiment, regardless of whether the processing box 100 is in a printing or non-printing state, the second force receiving portion 106 will always maintain contact with the pushing portion 41 of the imaging device. This allows the pushing portion 41 of the imaging device to be buffered by the elastic deformation of the engaging portion 107 of the second force receiving portion 106 when it moves instantaneously, thus avoiding direct and instantaneous hard contact between the pushing portion 41 and the second force receiving portion 106, which could lead to damage to both. However, alternatively, the engaging portion 107 can also be provided on the first force receiving portion 108, so that the pushing portion 41 is always in contact with the first force receiving portion 108. Alternatively, the engaging portion 107 can be provided on both the first force receiving portion 108 and the second force receiving portion 106, so that the pushing portion 41 is always in contact with both the first force receiving portion 108 and the second force receiving portion 106. This is not a limitation.

[0163] Example 10

[0164] like Figures 53-58 As shown, the processing box 400 of Embodiment 10 of the present invention will be described next. The same parts as those in the above embodiments will not be repeated in this embodiment. The difference is that some basic structures of the processing box 400 are different.

[0165] The processing box 400 includes an electrode 414 disposed on the housing 410. Specifically, the electrode 414 is disposed on the second cover 412 of the second housing 410b. The electrode 414 has an electrode electrical contact surface 414a that can make electrical contact with the power supply component of the imaging device. In a first direction, the electrode electrical contact surface 414a is disposed at the second end of the housing 410. The electrode electrical contact surface 414a is configured to supply the power to the charging roller. That is, the electrode 414 can receive the power of the imaging device and supply the received power to the charging roller to ensure that the charging roller can charge the photosensitive drum 405. Furthermore, the processing box 400 also includes a chip 413, which has a chip electrical contact surface 413a that makes electrical contact with the electrical contacts of the imaging device. In the first direction, the chip electrical contact surface 413a is disposed at the second end of the housing, that is, at a different end from the first coupling member 420 and the second coupling member 421. This arrangement ensures that the chip electrical contact surface 413a is sufficiently far away from the first coupling member 420 and the second coupling member 421, reducing the impact of vibrations caused by the rotation of the first coupling member 420 and the second coupling member 421 on the chip electrical contact surface 413a, and helping to improve the electrical contact stability between the first coupling member 420 and the second coupling member 421 and the imaging device. The chip electrical contact surface 413a and the electrode electrical contact surface 414a are spaced a certain distance apart to avoid mutual electrical interference between them. Moreover, in the first direction, compared to the electrode electrical contact surface 414a, the chip electrical contact surface 413a is disposed at a position further away from the first end of the housing 410.

[0166] Furthermore, the processing cartridge 400 includes a first cleaning member 408 supported on the second housing 401b and a second receiving cavity 401b4 disposed on the second housing 401b. Specifically, the first cleaning member 408 is preferably a cleaning scraper, felt, or sponge. One end (made of metal) is supported on the second housing 401b, and the other end (made of rubber) contacts the outer surface of the photosensitive drum 405 to scrape off the waste developer residue on the outer surface of the photosensitive drum 405 after transfer, thereby cleaning the photosensitive drum 405 and improving print quality. Finally, the scraped developer is collected in the second receiving cavity 401b4 of the second housing 401b. Therefore, this embodiment, by providing the first cleaning member 408 and the second receiving cavity 401b4, can clean the photosensitive drum 405 and collect the waste developer, which helps to improve the print quality of the processing cartridge 400.

[0167] Furthermore, in the actual printing process, there may be a situation where there is enough waste developer on the photosensitive drum 308 and some waste developer is already present on the first cleaning member 408, making it impossible for the cleaning member to completely scrape off all the residual waste developer on the photosensitive drum 405. In this case, the rotating photosensitive drum 405 will adhere some of the residual waste developer to the charging roller 409 through close contact. Therefore, when this situation occurs, on the one hand, it will affect the charging uniformity of the charging roller 409 charging the photosensitive drum 405, and on the other hand, it will also cause the waste developer on the charging roller 409 and the waste developer on the photosensitive drum 405 to contaminate each other, thereby affecting the cleanliness of their outer surfaces and the printing effect of the processing cartridge 400. Therefore, it is necessary to solve this potential problem, as a preferred embodiment in this example 4. In one embodiment, the processing cartridge 400 further includes a second cleaning member 411 disposed on the second housing 401b. The second cleaning member 411 is preferably felt or sponge, which can contact the outer surface of the charging roller 409 to facilitate cleaning of the outer surface of the charging roller 409. In this way, both the photosensitive drum 405 and the charging roller 409 can be cleaned by the cleaning member, and the cleanliness of their outer surfaces is improved, thereby improving the printing quality of the processing cartridge 400. Optionally, the second cleaning member 411 can also be configured as a cleaning blade. In this case, the waste developer scraped off by the cleaning blade can also enter the second receiving cavity 401b4 to complete the collection of waste developer. It is worth mentioning that the second cleaning member 411 in this embodiment 10 can also be used in any of the embodiments 1-9 above, which will not be described again here.
