Description

[0001] This utility model claims the priority of a Chinese prior application with an application date of July 19, 2023, an application number of 202321913199.8, and an invention title of "Processing Cartridge". All the content of this prior application is cross-referenced in this application. Technical Field

[0002] This utility model relates to the field of electrophotographic imaging, and particularly to a processing cartridge that is detachably installed in an electrophotographic imaging device. Background Art

[0003] There is a conventional drawer-type imaging device. In the imaging device, there is a tray that can be pulled in the direction close to the user and pushed in the direction away from the user. When the tray is pulled out, the processing cartridge is first installed on the tray, then the tray is pushed towards the inside of the imaging device, and finally the door cover is closed. The processing cartridge charges the surface of the photosensitive member in contact with the charging member by using a rotatably arranged charging member therein, and forms text or an image on the imaging medium through steps such as exposure, development, and transfer. Therefore, the processing cartridge is also provided with a charging electrode for receiving power from the imaging device and supplying it to the charging member.

[0004] The imaging device is also provided with a top plate linked to the door cover. The top plate is further provided with a power output member that can be in electrical contact with the charging electrode. As the door cover is closed, the top plate moves downward and abuts against the processing cartridge, and the power output member is in electrical contact with the charging electrode, finally positioning the processing cartridge in the imaging device. At the same time, the charging electrode can receive the power output by the power output member; conversely, when the door cover is opened, the top plate moves upward away from the processing cartridge, and the tray can be pulled out, and at the same time, the charging electrode is disengaged from the power output member.

[0005] Generally, the processing cartridge is also provided with a chip that can establish a communication connection with the imaging device. The top plate is provided with a contact pin that can be in electrical contact with the chip. The contact pin is arranged to be retractable. As the top plate moves downward, the contact pin abuts against the chip to achieve electrical contact. To simplify the circuit complexity inside the imaging device, the chip and the charging electrode are arranged at the same longitudinal end of the processing cartridge. When the processing cartridge reaches the predetermined installation position with the tray, the electrical contact portion for electrical contact with the contact pin and the charging electrode in the chip are both fixed in a manner facing upward (the top plate). In this way, the contact between the contact pin and the electrical contact portion and the contact between the power output member and the charging electrode can be achieved simultaneously.

[0006] Generally, the processing cartridge is further provided with a conductive member that can be electrically connected to the imaging device. The conductive member is mounted on a support member located at the end of the processing cartridge. The conductive member can receive the power provided by the imaging device and supply it to a developing member rotatably provided in the processing cartridge, a powder feeding member in contact with the developing member, and a blade in contact with the developing member. However, the existing conductive member is mounted from the outside of the support member (the side away from the developing member), and multiple fastening positions need to be provided, resulting in a complex structure and inconvenient assembly.

[0040] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0041] [Overall structure of the processing box]

[0042] Figure 1 It is a three-dimensional diagram of the processing box involved in the utility model.

[0043] The processing box C can be installed in an image forming device in a detachable manner. The image forming device is provided with the above-mentioned drawer-type tray and a top plate that can move with the movement of the door cover, and a movable contact pin 95 and a power output member 96 (such as Figure 4 As shown in the figure, when the processing box C arrives inside the imaging device along with the tray, the top plate moves downward and abuts against the processing box C while the door cover is closed. Therefore, the contact pin 95 and the power output member 96 can contact the corresponding components in the processing box C at the same time. For a specific description of the imaging device, please refer to the Chinese invention patent application with publication number CN113574469A.

[0044] The processing cartridge C includes a first unit 100 and a second unit 200 that are combined with each other, and a first end cap 300 and a second end cap 400 located at two longitudinal ends of the processing cartridge C. The first unit 100 and the second unit 200 can be combined with each other through the first end cap 300 and the second end cap 400, or can also be combined by means such as pins and buckles. The first end cap 300 and the second end cap 400 can either be part of the first unit 100 or the second unit 200, or be components independent of the first unit 100 or the second unit 200, as long as they can combine the first unit 100 and the second unit 200. The developing roller 11 (as Figure 3 shown) is rotatably provided in the first unit housing 1 of the first unit 100, and the photosensitive drum 21 is rotatably provided in the second unit housing 2 of the second unit 200. When the processing cartridge C is operating, the photosensitive drum 21 contacts the developing roller 11, and the developing roller 11 supplies the toner stored in the first unit 100 to the photosensitive drum 21.

[0045] For the convenience of the following description, it is defined herein that the side of the processing cartridge C where the photosensitive drum 21 and the developing roller 11 are installed points to the side where the photosensitive drum 21 and the developing roller 11 are not installed as the upper side, and the side opposite to the upper side is the lower side. The processing cartridge C is installed from top to bottom in the up-down direction onto the tray of the imaging device. The direction from the first unit 100 to the second unit 200 is the front, and the side opposite to the front is the rear. The side of the processing cartridge C that receives the driving force from the imaging device is the left side, and the side opposite to the left side is the right side. The right side is the side for receiving power, and the left side can also be referred to as the driving end C1, and the right side can also be referred to as the non-driving end / conductive end C2. The first end cap 300 is installed at the driving end C1, and the second end cap 400 is installed at the non-driving end C2. A first driving force receiving member (not shown) for receiving the driving force for the developing roller 11 and a second driving force receiving member (not shown) for receiving the driving force for the photosensitive drum 21 both expose from the first end cap 300.

[0046] Both the developing roller 11 and the photosensitive drum 21 extend in the left-right direction, and the left-right direction can also be referred to as the longitudinal direction. The front-back direction and the up-down direction both intersect with the left-right direction. Preferably, the left-right direction, the front-back direction, and the up-down direction are perpendicular to each other. After the processing cartridge C is installed on the tray, the tray is pushed backward into the imaging device in the front-back direction.

[0047] The processing cartridge C further includes a separation contact mechanism 5 located therein (as Figure 2As shown, when the processing cartridge C does not need to work in the imaging device, the separation contact mechanism 5 receives a separation force from the imaging device to force the developing roller 11 and the photosensitive drum 21 to separate from each other, and the contamination of the surface of the photosensitive drum 21 or the deformation of the surface of the developing roller 11 is suppressed. Among them, the separation contact mechanism 5 is arranged near the longitudinal end of the processing cartridge C, and the number thereof can be one or more; further, the processing cartridge C further includes a reset member 16 (such as Figure 2 As shown, when a separation force is applied to the processing cartridge C, the reset member 16 undergoes elastic deformation. When the separation force is withdrawn, the reset member 16 releases elastic force, and the developing roller 11 and the photosensitive drum 21 return to the position of contacting each other.

[0048] The processing cartridge C further includes a chip 7 (such as Figure 2 As shown) for establishing a communication connection with the imaging device. The chip 7 includes a storage portion (not shown) storing information of the processing cartridge C and an electrical contact portion 71 electrically connected to the storage portion. Among them, the electrical contact portion 71 and the storage portion can be integrated on the same plate or separately arranged, but the electrical contact portion 71 always faces upward and is exposed upward of the processing cartridge C. When the door is closed, the electrical contact portion 71 is in electrical contact with the contact pin 95.

[0049] Further, the processing cartridge C further includes a charging roller 24 rotatably arranged in the second unit housing 2 and a charging electrode assembly 8 (such as Figure 3 As shown) for supplying power to the charging roller 24. The charging electrode assembly 8 is used for electrical contact with the power output member 96. The charging roller 24 is rotatably supported by a bracket 26. A spring 25 is arranged between the bracket 26 and the second unit housing 2. By the pushing of the spring 25, the charging roller 24 remains in contact with the photosensitive drum 21. The charging roller 24 includes a metal shaft 241 and a coating layer 242 coated on the surface of the metal shaft 241. When the processing cartridge C works, the metal shaft 241 receives power from the imaging device, so that the charging roller 24 charges the surface of the photosensitive drum 21. When the laser beam carrying imaging information irradiates the charged surface of the photosensitive drum 21, an electrostatic latent image is formed in the area where imaging is required. Subsequently, the toner on the surface of the developing roller 11 develops the electrostatic latent image. In some embodiments, the charging electrode assembly 8 supplies power to the charging roller 24 by directly abutting against the metal shaft 241. In other embodiments, the bracket 26 can be made of a conductive material. In this way, the charging electrode assembly 8 supplies power to the charging roller 24 by abutting against the spring 25 or the bracket 26. Hereinafter, the description of the electrical connection between the charging electrode assembly 8 and the charging roller 24 includes any one of the above three abutting methods.

[0050] Preferably, the electrical contact portion 71 and the charging electrode assembly 8 are disposed at the non-driving end C2. On the one hand, it can prevent the vibration at the driving end C1 from making the electrical contact between the electrical contact portion 71 and the contact pin 95 and the electrical contact between the charging electrode assembly 8 and the power output member 96 unstable. On the other hand, it can simplify the circuit complexity inside the imaging device, so that the components (such as the above-mentioned contact pin 95 and power output member 96) for supplying power to the processing cartridge C inside the imaging device are all disposed at the non-driving end C2 of the processing cartridge C.

[0051] In some embodiments, the setting positions of the electrical contact portion 71 and the charging electrode assembly 8 should not be limited. For example, the electrical contact portion 71 and the charging electrode assembly 8 can be respectively or together disposed on any one of the first unit housing 1, the second unit housing 2, and the second end cap 400.

[0052] The following takes the case where the electrical contact portion 71 and the charging electrode assembly 8 are both disposed on the second end cap 400 as an example for illustration.

[0053] [Embodiment 1]

[0054] Figure 2 is a perspective view of the processing cartridge according to Embodiment 1 of the present invention; Figure 3 is a side view of the processing cartridge according to Embodiment 1 of the present invention when viewed from left to right in the left-right direction after hiding a part of the components; Figure 4 is a perspective view of the top plate in the imaging device applicable to the processing cartridge of the present invention; Figure 5A is a simplified side view of the processing cartridge according to Embodiment 1 of the present invention when viewed from left to right in the left-right direction before contacting the top plate; Figure 5B is a simplified side view of the processing cartridge according to Embodiment 1 of the present invention when viewed from left to right in the left-right direction after contacting the top plate.

[0055] Before describing the processing cartridge C of this embodiment, first describe the power output member 96. As Figure 4 shown, taking the state where the processing cartridge C is installed in the imaging device as a reference, the top plate 94 also has the above-mentioned up-down direction, left-right direction, and front-back direction. The contact pin 95 and the power output member 96 are both exposed downward. The number of the contact pins 95 corresponds to the number of the electrical contact portions 71 of the chip 7. The power output member 96 is provided as a conductor protruding downward from the top plate 94, and has a front conductive surface 962 facing forward, a rear conductive surface 961 facing backward, a left conductive surface 963 facing left, a right conductive surface 965 facing right, and a lower conductive surface 964 facing downward.

[0056] As Figure 3As shown, the charging electrode assembly A8 includes a power receiving portion A81 for receiving power and a power transfer portion A82 for electrically connecting to the charging roller 24. The power receiving portion A81 is electrically connected to the power transfer portion A82. Preferably, the power receiving portion A81 and the power transfer portion A82 are integrally formed. In this embodiment, the power receiving portion A81 and the power transfer portion A82 are integrally formed by a conductive steel sheet.

[0057] Furthermore, as Figure 2 shown, the second end cap 400 is further provided with an electrical contact cavity 401. When the door of the imaging device is closed, at least the power receiving portion A81 is located in the electrical contact cavity 401. In this embodiment, the power receiving portion A81 is fixedly installed in the electrical contact cavity 401. Specifically, the power receiving portion A81 is fixed to the front side of the electrical contact cavity 401.

[0058] Before the door of the imaging device is closed, the top plate 94 is in the position as Figure 5A shown. At this time, in the up and down direction, the top plate 94 does not abut against the processing cartridge C, the contact pin 95 is separated from the electrical contact portion 71, and the power output member 96 is also separated from the power receiving portion A81. As the door of the imaging device is closed, the top plate 94 gradually moves downward. When the door is completely closed, the top plate 94 abuts against the imaging device, the contact pin 95 abuts against the electrical contact portion 71 and retracts into the interior of the top plate 94, at least a part of the power output member 96 enters the electrical contact cavity 401, and the front conductive surface 962 contacts the power receiving portion A81. Finally, the electrical contact portion 71 is electrically connected to the contact pin 95, the power receiving portion A81 is also electrically connected to the power output member 96, and the electrical connection between the processing cartridge C and the imaging device becomes stable. At the same time, by using the abutment of the contact pin 95 against the electrical contact portion 71, the processing cartridge C can be stably positioned in the imaging device.

[0059] As a deformation mode of this embodiment, the power receiving portion A81 can also be provided at the rear side of the electrical contact cavity 401. When at least a part of the power output member 96 enters the electrical contact cavity 401, the rear conductive surface 961 of the power output member 96 contacts the power receiving portion A81. At this time, the force that the power receiving portion A81 may exert on the power output member 96 will be towards the front. This method can also ensure that the electrical connection between the processing cartridge C and the imaging device becomes stable.

[0060] As described above, when the door is closed and the top plate 94 abuts against the processing cartridge C, at least a part of the power output member 96 enters the electrical contact cavity 401, and the power receiving portion A81 abuts against the side conductive surface (not the lower conductive surface) of the power output member 96. The force that the power receiving portion A81 may exert on the power output member 96 is backward, and the top plate 94 will only receive the upward reaction force exerted by the electrical contact portion 71 on the contact pin 95. Therefore, the contact between the electrical contact portion 71 and the contact pin 95 and the contact between the power receiving portion A81 and the power output member 96 can be stably achieved, and the electrical connection between the processing cartridge C and the imaging device will also become stable.

[0061] [Embodiment 2]

[0062] Figure 6 It is a perspective view of some components in the processing cartridge according to the second embodiment of the present invention; Figure 7 It is a partial perspective view after the processing cartridge according to the second embodiment of the present invention contacts the top plate.

[0063] Compared with the first embodiment, the contact position between the charging electrode assembly B8 and the power output member 96 in this embodiment is different. As Figure 6 shown, the power receiving portion B81 is fixedly installed on the right side of the electrical contact cavity 401. As Figure 7 shown, when the top plate 94 abuts against the processing cartridge C downward, at least a part of the power output member 96 enters the electrical contact cavity 401, the contact pin 95 is electrically connected to the electrical contact portion 71, and at the same time, the right conductive surface 965 of the power output member 96 contacts the power receiving portion B81 to achieve electrical connection.

[0064] Similarly, the force that the power receiving portion B81 may exert on the power output member 96 in this embodiment is to the left, and the top plate 94 will only receive the upward reaction force exerted by the electrical contact portion 71 on the contact pin 95. Therefore, the contact between the electrical contact portion 71 and the contact pin 95 and the contact between the power receiving portion B81 and the power output member 96 can be stably achieved, and the electrical connection between the processing cartridge C and the imaging device will also become stable.

[0065] As a deformation mode of this embodiment, the power receiving portion B81 can also be arranged on the left side of the electrical contact cavity 401. When at least a part of the power output member 96 enters the electrical contact cavity 401, the left conductive surface 963 of the power output member 96 contacts. At this time, the force that the power receiving portion B81 may exert on the power output member 96 will be toward the right. This method can also ensure that the electrical connection between the processing cartridge C and the imaging device becomes stable.

[0066] [Embodiment 3]

[0067] Figure 8 It is a perspective view of some components in the processing cartridge according to the third embodiment of the present invention; Figure 9FIG. 0 is a simplified side view of the processing cartridge according to Embodiment 3 of the present invention when viewed from left to right in the left-right direction after hiding some components before contacting the top plate; Figure 10 FIG. 1 is a simplified side view of the processing cartridge according to Embodiment 3 of the present invention when viewed from left to right in the left-right direction after contacting the top plate.

[0068] As shown in the figure, in this embodiment, the charging electrode assembly C8 includes a power receiving portion C81, a power transmission portion C82, and a toggling member C83. The toggling member C83 is used to toggle the power receiving portion C81 so that the power receiving portion C81 is switched from a first state where power cannot be received to a second state where power can be received. Thus, the power of the power output member 96 is sequentially transmitted to the charging roller 24 through the toggling member C83, the power receiving portion C81, and the power transmission portion C82, or the power is sequentially transmitted to the charging roller 24 through the power receiving portion C81 and the power transmission portion C82.

[0069] In this embodiment, the toggling member C83 is arranged to be rotatable about a rotation axis, and the rotation axis is not limited. For example, the rotation axis can be parallel to the left-right direction, can also be parallel to the front-back direction, and can also be parallel to the up-down direction. The power receiving portion C81 and the power transmission portion C82 are arranged as a tension spring formed integrally. The power receiving portion C81 and the power transmission portion C82 are respectively two ends of the tension spring. Among them, the power receiving portion C81 is connected to the toggling member C83, and the power transmission portion C82 is electrically connected to the charging roller 24.

[0070] In this embodiment, the rotation axis of the toggle member C83 is parallel to the left-right direction, and the toggle member C83 is made of a non-conductive material. As shown in the figure, the toggle member C83 includes a compressed portion C831, a toggle portion C832, and a rotating portion C833, and the compressed portion C831 and the toggle portion C832 are formed to protrude from the rotating portion C833. Before the door cover is closed, or before the top plate 94 abuts against the processing box C, the power receiving part C81 is pulled upward by the tension spring (power receiving part C81), and the compressed part C831 faces downward. Preferably, the compressed part C831 protrudes from the second unit shell 2; when the top plate 94 begins to abut against the processing box C, the compressed part C831 is compressed by the top plate 94 and rotates around the rotation axis, and the compressed part C831 moves upward. At the same time, the toggle part C832 drives the power receiving part C81 to move downward; when the door cover is completely closed, the compressed part C831 is pressed to the bottom by the top plate 94, and at least a part of the power output member 96 enters the electrical contact cavity 40. 1. The toggle portion C832 drives the power receiving portion C81 to contact the power output member 96, and at the same time, the contact pin 95 is electrically connected to the electric contact portion 71; the power receiving portion C81 can contact any one of the side conductive surfaces of the power output member 96 (including the front conductive surface 962, the rear conductive surface 961, the left conductive surface 963 and the right conductive surface 965). At this time, the force that the power receiving portion C81 may apply to the power output member 96 is not upward, so the contact between the electric contact portion 71 and the contact pin 95 and the contact between the power receiving portion C81 and the power output member 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device also becomes stable.

[0071] It should be noted that the power receiving part C81 in this embodiment can also contact the lower conductive surface 964 of the power output member 96. In this case, although the force applied to the power output member 96 by the power receiving part C81 may be upward, the power receiving part C81 is one end of a tension spring. Therefore, even if the upward pressure applied by the power output member 96 to the power receiving part C81 is large, the power receiving part C81 can offset the large pressure by contracting upward, so that the contact between the power output member 96 and the power receiving part C81 will not weaken the electrical connection between the electrical contact part 71 and the contact pin 95. Therefore, in this case, the contact between the electrical contact part 71 and the contact pin 95 and the contact between the power receiving part C81 and the power output member 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device also becomes stable.

[0073] Figure 11 It is a three-dimensional diagram of some components in the processing box involved in the fourth embodiment of the utility model; Figure 12 It is a simplified side view of the processing box involved in the fourth embodiment of the present utility model when viewed from left to right along the left-right direction after contacting with the top plate.

[0074] Compared with Embodiment 3, the toggle member D83 in this embodiment is made of metal. Therefore, in this embodiment, when the top plate 94 abuts against the processing cartridge C, the toggle member D83 does not have to toggle the power receiving portion D81 into contact with the power output member 96. Instead, the toggle member D83 itself contacts the power output member 96, and then the toggle member D83 transfers the power to the power receiving portion D81. Preferably, the toggling portion D832 of the toggle member D83 contacts the power output member 96. In this way, the movement path of the power receiving portion D81 in the processing cartridge C can be reduced, or even the power receiving portion D81 does not have to move, as long as it is ensured that the power receiving portion D81 can maintain good electrical contact with the movable toggle member D83.

[0075] Similar to Embodiment 3, when the top plate 94 abuts against the processing cartridge C, at least a part of the power output member 96 enters the electrical contact cavity 401, and the toggle member D83 can contact any conductive surface of the power output member 96. Preferably, the toggling portion D832 of the toggle member D83 contacts the side conductive surface of the power output member 96. Therefore, the contact between the electrical contact portion 71 and the contact pin 95 and the contact between the power receiving portion D81 and the power output member 96 can be stably achieved, and the electrical connection between the processing cartridge C and the imaging device also becomes stable.

[0076] [Embodiment 5]

[0077] Figure 13A and Figure 13B are respectively simplified side views of the processing cartridge according to Embodiment 5 of the present invention when viewed from left to right in the left-right direction before and after contacting the top plate.

[0078] In this embodiment, the charging electrode assembly E8 includes a power receiving portion E81, a power transmission portion E82, and a toggle member E83. Among them, the power transmission portion E82 is electrically connected to the charging roller 24, and the toggle member E83 is used to convert the power receiving portion E81 from a first state where power cannot be received to a second state where power can be received. Different from Embodiment 3 and Embodiment 4, at least a part of the toggle member E83 in this embodiment is arranged as a rack that can slide in the up-down direction.

[0079] As shown in the figure, the toggle member E83 includes a rack E831, a toggling portion E832, and a rotating portion E833. Among them, the rack E831 extends in the up-down direction, the toggling portion E832 protrudes from the rotating portion E833, and the rack E831 and the rotating portion E833 are provided with teeth that can mesh with each other. At the same time, the power receiving portion E81 is connected to the toggle member E83 / toggling portion E832, and the power transmission portion E82 is electrically connected to the charging roller 24.

[0080] According to the records of the third and fourth embodiments, the toggle portion E832 can be made of either a conductive material or a non-conductive material. When the top plate 94 is not in contact with the processing box C, preferably, the rack E831 protrudes upward from the second end cover 400 / the second unit housing 2. As the top plate 94 moves downward toward the processing box C, the upper end of the rack E831 begins to be contacted by the top plate 94, and the rack E831 moves downward. Then, the rotating portion E833 rotates in the direction indicated by r5, and the toggle portion E832 itself or the toggle portion E832 drives the power receiving portion E81 to move upward, as shown in FIG. Figure 13B As shown, when the top plate 94 presses the rack E831 to move to the bottom, at least a portion of the power output component 96 enters the electrical contact cavity 401, and the toggle portion E832 drives the power receiving portion E81 to contact the power output component 96, or the toggle portion E832 itself contacts the power output component 96, and at the same time, the contact pin 95 is electrically connected to the electrical contact portion 71; the power receiving portion E81 / toggle portion E832 can contact any conductive surface of the power output component 96, so the contact between the electrical contact portion 71 and the contact pin 95 and the contact between the power receiving portion E81 and the power output component 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device also becomes stable.

[0081] [Example 6]

[0082] Figure 14A and Figure 14B They are simplified side views of the processing box involved in the sixth embodiment of the present invention before and after contact with the top plate, when viewed from left to right along the left-right direction.

[0083] Compared with the fifth embodiment, in this embodiment, the toggle part F832 of the toggle member F83 is also set as a rack, the rotating part E833 is located between the rack E831 and the rack E832, the toggle part F832 can be made of conductive material or non-conductive material, the power receiving part F81 is connected to the rack F832, and the rack F832 is used to convert the power receiving part F81 from a first state in which power cannot be received to a second state in which power can be received. When the top plate 94 approaches the processing box C, at least a part of the power output member 96 gradually enters the electrical contact chamber 401, the rack E831 gradually moves downward, and the rack E832 gradually moves upward through the rotating part E833. Finally, the power receiving part E81 contacts the power output member 96, or the rack E832 itself contacts the power output member 96. At the same time, the contact pin 95 is electrically connected to the electrical contact part 71; the power receiving part F81 / the toggle part F832 can contact any conductive surface of the power output member 96. Therefore, the contact between the electrical contact part 71 and the contact pin 95 and the contact between the power receiving part F81 and the power output member 96 can be stably achieved, and the electrical connection between the processing box C and the imaging device also becomes stable.

[0084] As a variant of the above embodiment, at least a part of the separation contact mechanism 5 can also serve as the toggling member. During the movement of the top plate 94 towards the processing cartridge C, the top plate 94 interacts with the separation contact mechanism 5, thereby forcing at least a part of the separation contact mechanism 5 to convert the power receiving portion from the first state where power cannot be received to the second state where power can be received.

The inner side 501 is the side of the non-driving end support member 500 that is closer to the developing roller 11 or the powder feeding roller 12 in the left-right direction, and the outer side 502 is the side of the non-driving end support member 500 that is farther from the developing roller 11 or the powder feeding roller 12 in the left-right direction. Among them, the first engaging portion 503 and the second engaging portion 504 are formed as grooves / through holes that are recessed from the inner side 501 in a direction away from the developing roller 11. The first engaging portion 503 and the second engaging portion 504 can be respectively used to support the developing roller 11 and the powder feeding roller 12, and the first engaging portion 503 and the second engaging portion 504 can also be used to be combined with the conductive member 6. The third engaging portion 505 and the fourth engaging portion 506 are preferably positioning posts that extend leftward from the inner side 501 of the non-driving end support member 500. The third engaging portion 505 and the fourth engaging portion 506 are used to position the conductive member 6. Therefore, the third engaging portion 505 and the fourth engaging portion 506 are formed as at least a part of the positioning mechanism that is used to position the conductive member 6. The fifth engaging portion 507 is preferably a through hole that penetrates in the left-right direction and is used to expose a part of the conductive member 6 to be electrically connected to the imaging device.

[0091] As Figure 18A and Figure 18BAs shown, the conductive member 6 includes a power input portion 61, a power output portion 62 and a conducting portion 63 connecting the power input portion 61 and the power output portion 62, wherein the power input portion 61 is used to connect to the imaging device, and further, the power input portion 61 is used to cooperate with the fifth coupling portion 507, and is exposed from the fifth coupling portion 507 to connect to the imaging device to receive power, and the power output portion 62 is used to connect to the developing roller 11, the powder feeding roller 12 and the powder outlet knife 13 and output power, and the conductive member 6 is also provided with a first coupled portion 64 and a second coupled portion 65 coupled to the non-driving end support member 500, the first coupled portion 64 is used to cooperate with the third coupling portion 505, and the second coupled portion 65 is used to cooperate with the fourth coupling portion 506, and the power input portion 61 is configured to cooperate with the fifth coupling portion 507 so that the conductive member 6 is installed on the non-driving end support member 500.

[0093] [Embodiment 8]

[0094] Figure 20 This is a schematic diagram of the processing box involved in the eighth embodiment of the utility model after some components are hidden; Figure 21 It is a three-dimensional diagram of the processing box involved in the eighth embodiment of the utility model when it is cut along a plane parallel to the up-down direction and observed in the left-right direction.

[0095] like Figure 20 , Figure 21As shown, the first unit 100 includes a toner cartridge 100a for accommodating toner, a developing cartridge 100b for accommodating a developing roller 11 and a toner feeding roller 12. An outlet partition 100c is provided between the toner cartridge 100a and the developing cartridge 100b. An outlet port 100d is formed on the outlet partition 100c. The toner is transported to the developing cartridge 100b through the outlet port 100d and thus supplied to the photosensitive drum 21. Before the processing cartridge C is used, the outlet port 100c is sealed by a seal 16. Further, the space of the toner cartridge 100a is larger than that of the developing cartridge 100b. The seal 16 is welded to the side of the outlet partition 100c away from the developing roller 11 and the toner feeding roller 12, that is to say, the seal 16 is welded to the side of the outlet partition 100c facing the toner cartridge 100a. Since the space of the toner cartridge 100a is larger, the difficulty of welding the seal 16 is reduced and the design freedom is also improved. A part of the seal 16 is exposed from the end of the processing cartridge C. When the processing cartridge C is in use, the seal 16 can be pulled out from the outside of the processing cartridge C. Compared with the prior art in which the seal 16 is welded to the side of the outlet partition 100c close to the developing roller 11 and the toner feeding roller 12, this embodiment can avoid interference between the seal 16 and the toner feeding roller 12 or the developing roller 11.

[0096] Further, the first unit 100 is provided with a toner filling port 14 and a seal cover 15 for sealing the toner filling port 14. The toner filling port 14 is located above the seal 16. The toner filling port 14 can be used for adding toner. In this embodiment, the toner filling port 14 is provided at the non-driving end C2 of the processing cartridge C.

[0097] In this embodiment, the first unit housing 1 includes a face cover 1a and a main body 1b which are combined with each other. The toner cartridge 100a and the developing cartridge 100b are formed between the face cover 1a and the main body 1b. During assembly, the seal 16 can be welded first. One end of the seal 16 extends out of the processing cartridge C. Then the face cover 1a of the first unit housing 1 is welded so that the face cover 1a and the main body 1b are formed into one body. Finally, toner is filled through the toner filling port 14. When the processing cartridge C is in use, the seal 16 is pulled out first. Therefore, the operating space during welding the seal 16 is larger, the welding difficulty of the seal 16 can be reduced, and the design freedom is improved.
