Description

[0001] Case Separation Statement

[0002] This application is a divisional application of Chinese utility model patent application filed on July 10, 2024, with application number 202421634488.9 and invention title "Developer Box". Technical Field

[0003] This utility model relates to the field of electrophotographic imaging, and more particularly to a developing cartridge that can be detachably installed in an electrophotographic imaging device. Background Technology

[0004] A developing cartridge is a container holding developer, in which a stirring element for agitating the developer is rotatably mounted. When the developing cartridge is installed in an electrophotographic imaging device (hereinafter referred to as "imaging device"), electrostatic imaging technology is used to display the desired image or text on an imaging medium. To enable the device to know information such as the model number of the developing cartridge, existing developing cartridges are equipped with a detection device that can interact with the object being tested in the device.

[0005] Generally, the agitator is formed by injection molding. In actual products, the detection device includes multiple parts, and the agitator needs to transmit the driving force from the driving end to the detection end. Along the length of the developing cartridge, the agitator is set to extend from one end of the developing cartridge to the other end, which results in the agitator being long and narrow, making it easy to break during transmission. Utility Model Content

[0006] In view of this, the present invention provides a developing cartridge to prevent the stirring element from breaking, specifically as follows:

[0007] A developing cartridge, detachably mounted in an imaging device containing a test piece along a front-to-back direction, includes: a housing with a developer chamber for containing developer; a developing element rotatably disposed within the housing and having a first axis parallel to a first direction; a driving force receiving element located at one end of the developing cartridge and having a second axis parallel to the first direction; and a detection device including a driving assembly disposed at one end of the developing cartridge, an action assembly disposed at the other end of the developing cartridge, and a transmission element disposed between the driving assembly and the action assembly. After receiving a driving force, the driving assembly drives the transmission element to reciprocate in a direction parallel to the first direction to transmit the driving force to the action assembly, forcing the action assembly to reciprocate with the test piece. The tested components interact; wherein the front-back direction is perpendicular to the first direction, and the third direction is perpendicular to both the first direction and the front-back direction; wherein the front-back direction is perpendicular to the first direction, and the third direction is perpendicular to both the first direction and the front-back direction, and the transmission component is located outside the developer chamber; the transmission component includes a forced pusher disposed at one end of the developer cartridge, a transmission part disposed at the other end of the developer cartridge, and a moving part disposed between the forced pusher and the transmission part, the moving part being movable in the first direction; the transmission component includes a guide groove disposed on the housing, and the transmission part is guided by the guide groove to move along the first direction.

[0008] In some embodiments, along a third direction, the housing includes an upper housing located above and a lower housing located below, with the developer chamber located between the upper housing and the lower housing, wherein at least the developing element is rotatably disposed in the lower housing.

[0009] In some embodiments, the developing cartridge further includes a cover to prevent the transmission element from falling off, the cover covering the guide groove from above.

[0010] In some embodiments, the developing cartridge further includes a pair of guide plates configured to project upward from the housing, the guide plates and the guide groove cooperating to cause the transmission part to reciprocate along the first direction.

[0011] In some embodiments, the drive assembly includes a drive member and a counter member, the drive member being used to receive and transmit a driving force to the counter member, the counter member being used to interact with the transmission member; and along the first direction, at least a portion of the counter member is closer to the housing than the drive member.

[0012] In some embodiments, the counter is configured as a rotating body with partially missing teeth in its circumferential direction.

[0013] In some embodiments, the upper housing and the lower housing are welded together to form a welded surface, which, when viewed along the first direction, does not coincide with the driving force receiving member.

[0014] In some embodiments, the developing cartridge further includes a guide plate disposed below the housing, wherein the surface of the guide plate is planar along the first direction and consists of a plurality of adjacent planar surfaces along the front-back direction.

[0015] A developing cartridge having at least one of the above technical solutions, by placing the transmission component outside the developer containing cavity, prevents the transmission component from interfering with the developer during movement, thus avoiding developer leakage. At the same time, it can independently move the object being tested in the imaging device, separate from the stirring component inside the developing cartridge, thereby preventing the stirring component from breaking.

[0049] It should be understood that the various embodiments described below are not isolated from each other, and those skilled in the art can combine the structures of the following embodiments according to design requirements.

[0050] Example 1

[0051] [The overall structure of the developing chamber]

[0052] like Figure 1A , Figure 1B and Figure 1CAs shown, the developing cartridge 1 includes a housing 2 forming a developer chamber 10 and a rotating member 3 rotatably disposed in the housing 2. The rotating member 3 may be, for example, a developing member 31 for conveying developer outward, or a powder feeding member 32 arranged adjacent to the developing member 31 and conveying developer to the developing member 31, or a stirring member 33 located in the developer chamber 10. The stirring member 33 stirs the developer in the developer chamber 10, which on the one hand prevents the developer from clumping, and on the other hand conveys the developer toward the powder feeding member 32. The developing cartridge also includes a handle 23 connected to the housing 2. Along the installation direction, the developing member 31 and the handle 23 are located at opposite ends of the housing 2.

[0053] The developing element 31 rotates about a first axis L1, and the housing 2 extends along a first direction parallel to the first axis L1. The developing cartridge 1 also has a second direction perpendicular to the first direction and a third direction perpendicular to both the first and second directions. One end 51 of the first direction points to the left of the developing cartridge, and the other end 52 of the first direction points to the right of the developing cartridge. One end 53 of the second direction points to the front of the developing cartridge, and the other end 54 of the second direction points to the rear of the developing cartridge. One end 55 of the third direction points to the top of the developing cartridge, and the other end 56 of the third direction points to the bottom of the developing cartridge.

[0054] In the following text, the left end of the developing cartridge is the driving end, and the right end is the conductive end. The device to be tested 9 is located on the right side of the developing cartridge; therefore, the right end of the developing cartridge can also be referred to as the detection end. The developing cartridge 1 also includes a detection device 6, which has a portion located at the driving end, another portion located at the detection end, and a portion located between the driving end and the detection end. The driving force transmission assembly 4 is used to transmit the driving force received by the driving force receiver 41 located at the driving end to the rotating member 3 and the detection device 6.

[0055] The housing 2 has a left surface 21 facing left, a right surface 22 facing right, and a left end cover 27 and a right end cover 28 respectively coupled to the housing 2. The left end cover 27 faces the left surface 21, and the right end cover 28 faces the right surface 22. A portion of the driving force receiving member 41 is exposed outward from the left end cover, and a portion of the detection device 6 is exposed outward from the right end cover 28. Figure 1BAs shown, the right end cover 28 has an exposure port 281, the size of which is larger than the size of the component (hereinafter referred to as the functional component 63) of the detection device 6 located at the detection end; furthermore, the developing cartridge 1 also includes a developer adjusting member 29 fixedly installed on the housing 2, a conductive member 26 combined with the housing 2, and a chip assembly 11 installed on one of the housing 2, the left end cover 27, and the right end cover 28. The chip assembly 11 can be a chip that is simultaneously provided with a substrate, electrical contacts, and a storage part, or it can be a movable member that has a substrate, electrical contacts, a storage part, and can be movably connected to the electrical contacts. The chip assembly 11 is used to establish a communication connection with the imaging device.

[0056] The conductive element 26 is located at the detection end and includes a main body 26a and a power input part 26b disposed on the main body 26a. The main body 26a or the power input part 26b is fixedly connected to the housing 2. The power input part 26b is used to receive power from the device and supply it to the developing element 31.

[0057] The developer adjustment component 29 includes a blade holder 291 and a blade 292. The blade holder 291 is fixedly mounted on the housing 2, and the blade 292 is fixed on the blade holder 291 and used to contact the developing element 31 to adjust the developer thickness on the surface of the developing element 31. The blade holder 291 includes a first part 2911 and a second part 2912 connected to each other. The blade 292 is fixed on the second part 2912, and a bend 2913 is formed between the first part 2911 and the second part 2912 to enhance the strength of the blade holder 291. Figure 3G As shown, when viewed along the first direction, the bent portion 2913 is located outside the projection range of the driving force receiver 41, or in other words, the projection of the driving force receiver 41 does not pass through the bent portion 2913. This arrangement helps to reduce the impact of vibration generated when the driving force receiver 41 rotates on the bent portion 2913. As a result, the developer adjustment component 29 can be more stable during the developing / working process of the developing cartridge 1.

[0058] In some embodiments, the projection of the intermediate gear 46 along the first direction does not pass through the bend 2913, which can further reduce the vibration impact on the developer conditioning member 29.

[0059] In some embodiments, the first part 2911 can be omitted, that is, the blade holder 291 no longer has the first part 2911, and correspondingly, the bending part 2913 no longer exists. At this time, the structure of the developer adjustment member 29 can be simplified, the blade holder 291 is no longer "L" shaped, but "I" shaped, the blade 292 is still fixed on the blade holder 291, and the blade holder 291 can still be fixed on the housing 2; furthermore, in order to strengthen the strength of the blade holder 291, a reinforcing member can also be provided on the blade holder 291 that extends continuously or is intermittently arranged along the first square.

[0060] When the developing cartridge 1 is in operation, the developing element 31 needs to be aligned with the photosensitive element outside the developing cartridge so that the developer carried on the surface of the developing element 31 can reach / be supplied to the surface of the photosensitive element to achieve development. Therefore, it is advantageous for the developing cartridge 1 to be pushed towards the photosensitive element. Figure 1C and Figure 2 As shown, the developing cartridge 1 also includes at least one of a first forced push portion 2b1 and a second forced push portion 2b2 disposed at the rear of the developing cartridge. The first forced push portion 2b1 and the second forced push portion 2b2 are used to receive the forced push force from outside the developing cartridge, thereby forcing the developing element 31 and the photosensitive drum to remain in contact. The first forced push portion 2b1 is located on the left side of the housing 2, and the second forced push portion 2b2 is located on the right side of the housing 2. Specifically, the first forced push portion 2b1 protrudes to the left from the left side of the housing 2, and the second forced push portion 2b2 protrudes to the left from the right end cover 28. That is to say, along the first direction, the first forced push portion 2b1 and the second forced push portion 2b2 both protrude in the same direction. Therefore, the first forced push portion 2b1 and the second forced push portion 2b2 can also both protrude to the right. This structure is beneficial to the miniaturization of the developing cartridge 1.

[0061] In some embodiments, the developing cartridge 1 is further provided with a conductive bracket for supporting the conductive component 26, the conductive bracket being fixedly connected to the housing 2, and the second forced push portion 2b2 may also be provided on the conductive bracket.

[0062] [Right end cap]

[0063] like Figure 1B As shown, along the second direction, the right end cap 28 is located behind the conductive element 26. A portion 282 of the right end cap 28 is formed as a second forced push portion 2b2. A portion of the active component is exposed from the exposure port 281. When viewed along the first direction, the right end cap 28 does not coincide with the powder filling port 2a3 located at the detection end. When the developer in the developing cartridge is depleted, the user can directly replenish the developer into the developing cartridge without removing the right end cap 28. Along the third direction, the powder filling port 2a3 is located below the active component 63. For the active component, which is set in a protruding shape, when the user replenishes the developer into the developing cartridge, it will not interfere with the active component 63. The active component 63 and the powder filling port 2a3 can be observed by the user simultaneously, and the probability of damage to the active component 63 is greatly reduced. Along the first direction, the powder filling port 2a3 is located between the second forced push portion 2b2 / 282 and the conductive element 26.

[0064] [Guideboard]

[0065] When the developing cartridge 1 is in operation, the imaging medium (e.g., printing paper) will pass through the developing cartridge 1 from below in a second direction along a third direction. To maintain the stability of the movement path of the imaging medium, the developing cartridge 1 also includes a guide plate 2d disposed below the housing 2, such as... Figure 1C As shown, the guide plate 2d has a continuous surface that extends substantially along a first direction and a second direction. Preferably, the surface of the guide plate 2d is smooth. More preferably, along the first direction, the surface of the guide plate 2d is planar, and along the second direction, the surface of the guide plate 2d consists of a plurality of adjacent planar surfaces, with each pair of adjacent planar surfaces intersecting at a line parallel to the first direction.

[0066] like Figure 1C As shown, the developing cartridge 1 also includes a reinforcing rib 10f extending downward from the housing 2. The guide plate 2d covers the reinforcing rib 10f, and the reinforcing rib 10f covered by the guide plate 2d is less likely to break.

[0067] The guide plate 2d and the housing 2 can be connected by adhesive, snap-fit, or welding.

[0068] [Drive force transmission components]

[0069] like Figure 2 As shown, the driving force transmission assembly 4 includes at least one of a driving force receiving member 41, a developing member driving member 42, a powder feeding member driving member 43, and a stirring member driving member 44. The developing member driving member 42 is coaxially arranged with the developing member 31 and is used to transmit the driving force from the driving force receiving member 41 to the developing member 31. The powder feeding member driving member 43 is coaxially arranged with the powder feeding member 32 and is used to transmit the driving force from the driving force receiving member 41 to the powder feeding member 32. The stirring member driving member 44 is coaxially arranged with the stirring member 33 and is used to transmit the driving force from the driving force receiving member 41 to the stirring member 33. When the stirring member driving member 44 is provided, the driving force transmission assembly 4 also includes a component located between the driving force receiving member 41 and the detection device 6. The idler wheel 45 between the driving force receiving components 41 transmits the driving force to the stirring component driving component 44 through the idler wheel 45, and then the stirring component driving component 44 transmits it to the detection device 6. In some embodiments, the driving force delivered to the detection device 6 can also come directly from any one of the driving force receiving component 41, the developing component driving component 42, the powder feeding component driving component 43, and the idler wheel 45. It is possible that the stirring component 33 can be configured to rotate about an axis parallel to the first direction, or it can be configured to reciprocate in a direction that is approximately parallel to the second direction. The driving force transmission method between the various driving components can be gear meshing transmission, belt transmission, friction wheel transmission, etc. Preferably, each driving component is configured as a gear.

[0070] The driving force receiving member 41 rotates about a second axis L2 parallel to the first direction. The detected member 9 is configured as a rod that can rotate about a third axis L3 parallel to the first direction, including a rotating part 93 and a first rod 91 and a second rod 92 connected to the rotating part 93. The second rod 92 is used to interact with the detection device 6, and the first rod 91 is used to be detected by the device.

[0071] In some embodiments, the powder feeding drive 43 is shielded by the left end cover 27 and is not exposed. In this case, the powder feeding drive 43 is located between the housing 2 and the left end cover 27 and is protected.

[0072] [Detection Device]

[0073] like Figure 2 As shown, the detection device 6 includes a drive assembly 61 disposed at the drive end, an action assembly 63 disposed at the detection end, and a transmission member 62 located between the drive assembly 61 and the action assembly 63. After receiving the driving force, the drive assembly 61 drives the transmission member 62 to move in a direction not perpendicular to the first direction, thereby forcing the action assembly 63 to interact with the detected component 9. Preferably, the movement direction of the transmission member 62 is parallel to the first direction. More preferably, the transmission member 62 reciprocates in a direction parallel to the first direction. In this way, the detection end of the developing cartridge does not need to be equipped with components such as gears and ratchets for transmitting driving force, or the number of components such as gears and ratchets for transmitting driving force is reduced. The structure of the detection end is simplified, and when the developing cartridge is assembled, only the assembly of the drive end needs to be focused on.

[0074] [Driver Components]

[0075] The drive assembly 61 includes a drive member 612 and a counter member 613. The counter member 613 rotates about a fourth axis L4 parallel to the first direction, and at least a portion of the counter member 613 is closer to the housing 2 than the drive member 612. The drive member 612 is used to engage with the stirring drive member 44 and receive driving force. Along the first direction, at least a portion of the counter member 613 is closer to the housing 2 than the stirring drive member 44. Figure 4A and Figure 4B As shown, along the first direction, at least the portion of the counter 613 that interacts with the transmission member 62 (the protrusion described below) is closer to the housing 2 / left surface 21 / right surface 22 than the drive member 612 and / or the stirring member drive member 44. Preferably, the counter 613 as a whole is closer to the housing 2 / left surface 21 / right surface 22 than the drive member 612 and / or the stirring member drive member 44. Furthermore, along the first direction, at least a portion of the counter 613 is closer to the housing 2 / left surface 21 / right surface 22 than the idler wheel 45 / driving force receiver 41. In this way, the size of the developing cartridge 1 in the first direction can be reduced, which is beneficial for miniaturizing the developing cartridge 1.

[0076] [Disconnect the driving force of the drive component]

[0077] The counting element 613 and the driving element 612 can be integrally formed or separate. After the detection is completed, the counting element 613 remains stationary by a separation mechanism provided in the developing cartridge 1. Specifically, when the counting element 613 and the driving element 612 are integrally formed, the counting element 613 as a whole will no longer receive driving force after the detection is completed. For example, the counting element 613 can be forced to move along the first direction or translated, so that the counting element 613 is detached from the driving source (any one of the driving force receiving element 41, developing element driving element 42, powder feeding element driving element 43, stirring element driving element 44, and idler wheel 45). In the case where the counting element 613 and the driving element 612 are formed separately, after the detection is completed, the counting element 613 and the driving element 612 may be disengaged, but the driving element 612 may not be disengaged from the driving source. Alternatively, the counting element 613 and the driving element 612 may be completely disengaged from the driving source. In some embodiments, regardless of whether the counting element 613 and the driving element 612 are formed integrally, the driving element 612 may be configured as a gear with a missing tooth. During the detection process, the gear part of the driving element 612 is opposite to the driving source and receives driving force. When the detection is completed, the missing tooth part of the driving element 612 is opposite to the driving source and does not receive driving force. The missing tooth part is a separation mechanism.

[0078] The counter 613 includes a chassis 613a, a connecting part 613b, a driving force receiving part 613c, and a plurality of protrusions provided on the chassis 613a. The counter 613 and the driving part 612 are connected to each other through the connecting part 613b. The driving force of the driving part 612 is transmitted to the counter 613 through the connection between the driving force output part 6122 provided on the driving part 612 and the driving force receiving part 613c provided on the counter 613.

[0079] When viewed along the rotation axis L4, the counter 613 is circular, and its radius R can vary between 5.0mm and 7.0mm, with an optimal value of 5.5mm to 6.5mm. Especially in structures with multiple gears at the drive end, if the diameter of the counter 613 is too large, it will be detrimental to the layout of other gears and lead to the failure of miniaturization of the developing cartridge 1. Conversely, if the diameter of the counter 613 is too small, the rotation speed of the counter 613 will increase, which will cause increased wear between the components of the drive force transmission assembly 4 and may even lead to the failure of the detection device 6.

[0080] When both the driving force receiver 41 and the driving member 612 are configured as gears, the gear tooth ratio between them is in the range of 0.7-1.3, preferably 0.8-1.1. In the case where the transmission member 62 adopts a translational scheme, this tooth ratio is beneficial for the miniaturization of the powder box end and improves the transmission accuracy.

[0081] [Structure of the counting component]

[0082] like Figure 5 As shown, the plurality of protrusions include a positioning protrusion 613d, a first actuating protrusion 613e, and a second actuating protrusion 613f, which are spaced apart along the circumferential direction of the chassis 613a. There is a flat portion 613g between two adjacent protrusions. The first flat portion 613g1 is between the positioning protrusion 613d and the first actuating protrusion 613e, and the second flat portion 613g2 is between the first actuating protrusion 613e and the second actuating protrusion 613f. The number of actuating protrusions can be increased or decreased according to the detection requirements of the detection device.

[0083] [Structure and Installation of Transmission Components]

[0084] The transmission member 62 includes a forced push portion 621 (forced push member 620) located at the drive end, a transmission portion 623 located at the detection end, and a moving portion 622 located between the forced push portion 621 and the transmission portion 623. The forced push portion 621 is used to receive the driving force from the driving force receiving member 41 and is combined with the counting member 613. The moving portion 622 is used to transmit the driving force to the transmission portion 623, and the transmission portion 623 is used to transmit the driving force to the actuating component 63. Further, the transmission member 62 also includes a reset member 67. When the transmission member 62 is pushed to the right / detection end, the reset member 67 accumulates a reset force. When the transmission member 62 is no longer pushed, the reset force forces the transmission member 62 to move / reset to the left / drive end. In some embodiments, the reset member 67 may not be a separate component. In this case, the reset of the transmission member 62 is driven by the reset of the detected member 9, which in turn drives the actuating component 63, and the actuating component 63 forces the transmission member 62 to reset.

[0085] like Figure 3 As shown, along a third direction, the housing 2 includes an upper housing 2a located above and a lower housing 2b located below. The developer chamber 10 is located between the upper housing 2a and the lower housing 2b. At least one of the developing element 31, the powder feeding element 32, and the stirring element 33 is rotatably disposed in the lower housing 2b. Figure 2 As shown, the guide groove 25 is located above the upper housing 2a, outside the developer chamber 10, and the guide groove 25 is exposed upward. The transmission member 62 is movably installed in the guide groove 25. In this way, the transmission member 62 will not interfere with the developer when it moves, and the leakage of the developer is also avoided.

[0086] In some embodiments, the developing element 31 and the guide groove 25 may also be both disposed on the upper housing 2a.

[0087] The developing cartridge 1 also includes a cover 24 to prevent the transmission component 62 from falling off. The cover 24 covers the guide groove 25 from above. On the one hand, the transmission component 62 will not fall off the guide groove 25, protecting the transmission component from external contact; on the other hand, it can improve the aesthetics of the developing cartridge. The cover 24 can be combined with the housing 2 by means of snap-fit, welding, bonding, magnetic attraction, etc.

[0088] In some embodiments, the cover 24 is also provided with abutting protrusions to prevent the counter 613 from reversing, so that the initial position at which the counter 613 begins detection can be determined.

[0089] In some embodiments, the cover 242 is also provided with a reset hole for allowing the counter 613 to be reset. When viewed in a third direction, a portion of the counter 613 is exposed through the reset hole, through which a user can reset the counter 613 using a finger or a special tool.

[0090] In some embodiments, the actuating component 63 has a surface for actuating the second lever 92, which, when viewed along the first direction, lies within the projection range of the counter 613, thus facilitating a reduction in the size of the developing cartridge in the second direction.

[0091] like Figure 3A As shown, the first forced push portion 2b1 and the second forced push portion 2b2 are disposed on the upper housing 2a. Along the first direction, the first forced push portion 2b1 and the second forced push portion 2b2 are spaced apart. Along the second direction, the first forced push portion 2b1 and the second forced push portion 2b2 both protrude downward from the rear direction of the upper housing 2a. This design can simplify the structure of the lower housing 2b, which has more components.

[0092] like Figure 3D As shown, the first forced push part 2b1 can also be provided on the left end cover 27, and the second forced push part 2b2 can also be provided on the right end cover 28. This design helps to simplify the structure of the housing 2.

[0093] The driving force receiver 41 includes at least one driving force receiving portion 41a spaced apart along its rotational direction. The driving force receiving portion 41a is configured to interact with a driving force output component in the imaging device to receive driving force from the driving force output component, and continue as follows... Figure 3D As shown, the driving force receiving part 41a is not blocked along the radial direction of the driving force receiving member 41, and the interference received by the driving force receiving member 41 can be reduced during the process of the driving force receiving member 41 and the driving force output member being combined.

[0094] like Figure 3BAs shown, in some embodiments, the driving force receiver 41 is further provided with an outer ring 41b. Along the radial direction of the driving force receiver 41, the outer ring 41b is located radially outside the driving force receiver 41a. In this case, the driving force receiver 41a will be blocked.

[0095] When the upper shell 2a and the lower shell 2b are joined by welding, the weld surface 2g formed by the welding of the upper shell 2a and the lower shell 2b is located on at least one side wall of the lower shell 2b. When viewed along the first direction, the weld surface 2g does not coincide with the driving force receiving member 41. Along the third direction, the weld surface 2g is located above the rotation axis L1 of the driving force receiving member 41.

[0096] like Figure 3B As shown, in another type of housing 2, the upper housing 2a and the lower housing 2b can also be joined together in a second direction. The guide groove 25 is provided on the upper housing 2a. When viewed along the first direction, the welding surface 2g does not coincide with the driving force receiver 41, or the welding surface 2g is located outside the projection range of the driving force receiver 41. Along the third direction, a portion of the welding surface 2g is located below the driving force receiver 41 (e.g., Figure 3C (as shown); In some embodiments, along a third direction, another portion of the welding surface 2g is located above the rotation axis L1 of the driving force receiver 41.

[0097] Specifically, along the second direction, the welding surface 2g is located behind the driving force receiver 41. In this way, not only can the impact of the vibration generated when the driving force receiver 41 rotates on the welding surface 2g be reduced, but also the lower housing 2b can be ensured to have enough space. At the same time, the volume of the developer chamber 10 can be maximized.

[0098] like Figure 3C As shown, the welding surface 2g can also be tilted relative to the second / third direction. Figure 3C The dashed line shows the welding surface 2g, which slopes from the upper front to the lower rear. It can be understood that the welding surface 2g can also slope from the upper rear to the lower front.

[0099] During the development process of the developing cartridge 1, the developing element 31 needs to be in contact with the photosensitive drum 40 outside the developing cartridge. However, when the developing cartridge 1 is not working or developing, the developing element 31 and the photosensitive drum 40 should not continue to maintain contact. For this reason, a scheme has emerged in which a force-applying element is provided in the imaging device, and a force-receiving element is provided in the developing cartridge 1. When the developing cartridge 1 is not working or developing, the force-applying element applies a separation force to the force-receiving element by abutting against it and holds it in place, thereby forcing the developing element 31 and the photosensitive drum 40 to separate from each other. When the developing cartridge 1 needs to work or develop again, the force-applying element no longer applies a separation force to the force-receiving element, and the developing element 31 and the photosensitive drum 40 come into contact with each other again.

[0100] Alternatively, when the developing cartridge 1 is not working / not developing, the force-applying member abuts against the force-receiving member, causing the developing element 31 and the photosensitive drum 40 to separate from each other. After the force-applying member and the force-receiving member disengage, the developing element 31 and the photosensitive drum 40 remain separated from each other by the retaining member provided in the developing cartridge. When the developing cartridge 1 needs to work / develop again, the force-applying member applies a restoring force to the force-receiving member, thereby forcing the developing element 31 and the photosensitive drum 40 to come into contact with each other again.

[0101] Regardless of the method used to achieve mutual contact and separation between the developing element 31 and the photosensitive drum 40, it is sufficient that at least a portion of the developing element 31 is not in contact with the photosensitive drum 40 when the developing cartridge 1 is not working / not developing. Figure 3E As shown, when the developing cartridge 1 is working / developing, the developing element 31 is in contact with the photosensitive drum 40, and the rotation axis L1 of the developing element 31 is parallel to the rotation axis L4 of the photosensitive drum 40; when the developing cartridge 1 is not working / not developing, the rotation axis L1 of the developing element 31 intersects with the rotation axis L4 of the photosensitive drum 40.

[0102] For example, a force receiver is provided in the developing cartridge 1. Along the first direction, this force receiver is located at the drive end or the detection end. When the force receiver receives a separation force, at the end where the force receiver is located, the developing element 31 and the photosensitive drum 40 separate from each other. At the end where the force receiver is not located, the developing element 31 and the photosensitive drum 40 may still be in contact or may be separated, but the distance between the rotation axis L1 of the developing element 31 and the rotation axis L4 of the photosensitive drum 40 will change along the first direction. Figure 3F An example is shown where a force receiver is provided at the drive end. In this example, after the force receiver receives the separation force, the developing element 31 rotates in the direction shown as r in the figure. At the drive end, the developing element 31 and the photosensitive drum 40 separate from each other, and the distance between the rotation axis L1 and the rotation axis L4 gradually changes along a first direction. Specifically, along the first direction, in the direction from the drive end to the detection end, the distance between the rotation axis L1 and the rotation axis L4 gradually decreases. Conversely, when the force receiver is provided at the detection end, after the force receiver receives the separation force, at the detection end, the developing element 31 and the photosensitive drum 40 separate from each other, and the distance between the rotation axis L1 and the rotation axis L4 gradually changes along the first direction. Specifically, along the first direction, in the direction from the detection end to the drive end, the distance between the rotation axis L1 and the rotation axis L4 gradually decreases.

[0103] In some embodiments, the force receiving element is a protrusion provided on the left end cap 27.

[0104] In some embodiments, the force receiving element may also be at least a part of the outer ring 41b, so that the force applying element directly applies a separation force or a restoring force to the outer ring 41b, and then the outer ring 41b drives the housing 2 to move relative to the photosensitive drum 40, thereby realizing the separation and contact between the developing element 31 and the photosensitive drum 40; in this modified mode, preferably, along the first direction, the outer ring 41b passes through the left end cover 27, and along the radial direction of the driving force receiving element 41, the outer ring 41b is not blocked by the left end cover 27, so that the force applying element can apply a separation force or a restoring force to the outer ring 41b.

[0105] [Structure of the functional component]

[0106] like Figures 6A-8F As shown, the actuating component 63 is configured to rotate about axis L5. During the rotation, the actuating component 63 interacts with the detected component 9. The axis of rotation of the actuating component 63 can be parallel to any one of the first direction, the second direction, and the third direction. In the following text, we take the example that the axis L5 is perpendicular to the first direction.

[0107] The actuating component 63 includes a rotating part 631, an actuating protrusion 632 extending from the rotating part 631, and a passive part 633. The actuating protrusion 632 is arranged in a non-linear manner along a direction perpendicular to the rotation axis L5; it can extend directly from the rotating part 631 or from the connecting part 636 connected to the rotating part 631. Figure 6C As shown, the actuating protrusion 632 is generally claw-shaped, and the groove / avoidance portion 6323 is provided in the actuating protrusion 632 and is recessed in a direction opposite to the rotation direction r3 of the actuating component 63. Figure 8B As shown, when the actuating protrusion 632 rotates with the rotating part 631, the actuating part 6324 of the actuating protrusion 632 will directly contact the surface 921 of the second rod 92 facing the actuating protrusion 632, instead of the actuating protrusion 62 first contacting the edge 922 and then contacting the surface 921. The edge 922 is the boundary line of the surface 921 on the side near the housing 2 / transmission member 62 / acting assembly 63.

[0108] Continue as Figure 6A and Figure 6B As shown, two surfaces 6321 / 6322 of different heights are formed above the actuating protrusion 632, with a height difference between them. This allows the contact point between the actuating protrusion 632 and the second rod 92 to be lowered. Extending from this, when the actuating protrusion 632 is configured to contact different positions of the tested component 9, the rotation speed of the tested component 9 can be varied, thus achieving the same detection function.

[0109] Figure 7A and Figure 7BAnother structure of the functional protrusion 632 is shown. Unlike the above embodiment, the functional protrusion 632 in this embodiment has an inclined surface 6325 and a plane 6326 on the side facing the second rod 92. The groove / avoidance portion 6323 extends in the plane 6326 and the inclined surface 6325 in a third direction. When the functional protrusion 632 contacts the second rod 92, the edge 922 will not contact the functional protrusion 632, and the functional portion 6324 will directly contact the surface 921.

[0110] The following is combined with Figure 9 Figures 10, 11, and 12. Figure 13 , Figure 14 A modified embodiment of the functional component 63 is described in Figure 15.

[0111] Transformation 1

[0112] like Figure 9 As shown, the actuating component 63 includes an actuating member 634 rotatable about a rotation axis L5 and a movable member 64 for driving the actuating member 634. The movable member 64 includes a base 641 and a movable part 642 movable relative to the base 641. The movable part 642 is configured to rotate only in one direction. The actuating member 634 includes a central shaft 6340 and a first lever 6341, a second lever 6342, and a ratchet 6343 coupled to the central shaft. The ratchet 6343 is driven by the movable part 642. Preferably, the ratchet 6343 is located in the central shaft. At one end of the spindle 6340, the first lever 6341 and the second lever 6342 extend radially outward from the surface of the spindle 6340 along the rotation axis L5. The first lever 6341 and the second lever 6342 are distributed at different axial positions, that is, the distance between the first lever 6341 and the second lever 6342 and any end of the spindle 6340 is different, or in other words, the first lever 6341 and the second lever 6342 have a height difference. Thus, the first lever 6341 and the second lever 6342 move the detected part 9 to different positions.

[0113] During the testing process, the transmission unit 623 moves to the right / test end and pushes the movable member 64. Subsequently, the movable member 642 pushes the ratchet 6343 to rotate, and the first lever 6341 or the second lever 6342 abuts against the second lever 92. When the transmission unit 623 stops pushing the movable member 64, the movable member 64 is pushed back to its original position by a component such as an elastic member. Figure 10AAs shown, the first lever 6341 contacts the surface 921 of the second lever at point Q1. As the ratchet 6343 is turned, the tested component 9 is pushed to rotate around the rotating part 93 in the direction shown by r until the first lever 6341 disengages from the second lever 92. As the ratchet 6343 continues to rotate, the second lever 6342 begins to contact the second lever 92 at point Q2. Compared to point Q1, point Q2 is farther away from the free end 923 of the second lever 92. That is to say, point Q2 is closer to the rotating part 93 than point Q1. With the rotational speed of the ratchet 6343 remaining constant, the tested component 9 will rotate faster under the push of the second lever 9342, thus creating the phenomenon of the tested component 9 being accelerated.

[0114] For the movable member 64, after the movable part 642 pushes the ratchet 6343, during the process of the elastic member forcing the movable member 64 to reset, the movable part 642 is supported by the ratchet 6343 and rotates, so that the movable part 643 can move into the position to push the ratchet 6343 again. In some embodiments, the movable member 64 is connected to the transmission part 623 and can move with the movement of the transmission part 623.

[0115] Transformation 2

[0116] In this modified embodiment, the actuating component 63 and the transmission component 62 are connected by a gear and rack, as shown in Figures 11 and 12. The transmission part 623 is configured as a rack, and the actuating component 63 includes a rotating part 631, an actuating protrusion 632 connected to the rotating part 631, and a driven part 633. The driven part 633 is configured as a gear, and preferably, the rotating part 631 and the gear 633 are coaxially arranged. When the transmission component 62 is pushed to the right / detecting end, the rack drives the gear to rotate, which in turn causes the rotating part 631 to drive the actuating protrusion 632 to swing. During the swinging of the actuating protrusion 632, the second rod 92 is actuated.

[0117] [Delayed motion of the counting component]

[0118] In some embodiments, the detected element 9 is configured to be driven by the driving force receiver 41 for a period of time before it is started to be moved. In this case, the rotational motion of the counter 613 needs to have a delay, that is, the driving force received by the driving force receiver 41 is not immediately transmitted to the counter 613.

[0119] In a feasible manner, along the rotation direction of the counter 613, the driving force output part 6122 of the drive member 612 and the driving force receiving part 613c provided in the counter 613 are spaced at a predetermined distance. In this way, when the drive member 612 starts to rotate, the driving force is not immediately transmitted to the counter 613. The counter 613 remains stationary. The counter 613 only starts to rotate when the driving force output part 6122 contacts the driving force receiving part 613c. The delay requirement of the counter 613 is achieved.

[0120] like Figure 13 As shown, the description takes the example of a drive member 612 being driven by a stirring member gear 44, and a counter member 613 being integrally formed with the drive member 612. The stirring member gear 44 is configured as a double gear. Along the first direction, the stirring member gear 44 includes a first gear 441 located on the left and a second gear 442 located on the right. The first gear 441 is a full-tooth gear, used to receive the driving force from the driving force receiving member 41. The second gear 442 is also a full-tooth gear, used to be opposite to the drive member 612 and to transmit the driving force to the drive member 612.

[0121] The driving component 612 is a toothed gear, meaning that on the same circumferential surface of the driving component 612, a portion of the circumferential surface of the driving component 612 is provided with teeth to form a toothed portion 612a, and another portion is without teeth to form a toothed portion 612b. Along the first direction, an intermediate portion 443 is formed between the first gear 441 and the second gear 442, and a turning portion 4411 is provided in the intermediate portion 443. Corresponding to the turning portion 4411, the driving component 612 is provided with a turned portion 612c. When the developing cartridge is assembled, along the first direction, the turning portion 4411 and the turned portion 612c are both located between the first gear 441 and the second gear 442. The turned portion 612c is located on the rotation path of the turning portion 4411, and the toothed portion 612b is opposite to the second gear 442. That is to say, even if the stirring gear 44 starts to rotate along the rotation direction r2 around the rotation axis L7, the driving component 612 will not be driven.

[0122] As the stirring gear 44 continues to rotate, the actuating part 4411 begins to actuate the actuated part 612c. At this time, the driving part 612 begins to rotate. When the actuating part 4411 disengages from the actuated part 612c, the toothed part 612a begins to mesh with the second gear 442. Thus, the driving part 612 / counting part 613 is driven by the stirring gear 44, and subsequently, the detected part 9 begins to be detected. The delay time of the driving part 612 / counting part 613 is the time required for the actuating part 4411 to begin contacting the actuated part 612c as the stirring gear 44 begins to rotate. It is understandable that the designer can also adjust the position of the actuating part 4411 according to the delay requirements of the equipment for the detected part 9, so that the moment when the actuating part 4411 begins to contact the actuated part 612c changes.

[0123] Preferably, the actuating part 4411 is integrally formed with one of the teeth of the first gear 441, thereby enhancing the strength of the actuating part 4411. Along the first direction, the actuating part 4411 is positioned closer to the second gear 442 than the teeth of the first gear 441.

[0124] [Acceleration of the tested item]

[0125] As described above, in some embodiments, the tested item 9 needs to be accelerated and moved when the detection period of the detection device 6 is about to end (the final stage of detection); otherwise, the developing cartridge will not be recognized by the device. To achieve the acceleration of the tested item 9, it can be achieved by accelerating the counter 613, accelerating the transmission 62, or moving the second lever 92 to different positions, as described above. Other implementation methods are described below.

[0126] Method 1

[0127] The following is combined with Figure 14 , Figure 15A and Figure 15B Another way to speed up the counter 613 is described.

[0128] In this embodiment, the counting component 613 and the driving component 612 are still integrated as an example. The separation mechanism includes an elastic pushing component 611. The driving component 612 is configured as a toothed gear. Furthermore, the driving component 612 also includes an arc surface 6124 coaxially arranged with the toothed gear and a straight surface 6125 adjacent to the arc surface. The elastic pushing component 611 is configured as a torsion spring. One end of the torsion spring abuts against the driving component 612, and the other end abuts against a component other than the driving component 612.

[0129] like Figure 15A As shown, before the detection device 6 reaches the final detection stage, the torsion spring 611 abuts against the arc surface 6124 and does not hinder the rotation of the drive member 612. When the detection device 6 reaches the final detection stage, the torsion spring 611 disengages from the arc surface 6124 and begins to abut against the straight surface 6125. During the process of the torsion spring 611 changing its contact surface, the torsion spring 611 releases torque, thereby forcing the drive member 612 to accelerate its rotation. Furthermore, the drive member 612 is also provided with an opening 6123 to facilitate the user to reset the torsion spring 611 from the outside.

[0130] Method 2

[0131] The acceleration of the driving member 612 can also be achieved by setting the second gear 442 of the stirring member gear 44 as a toothless gear, with the diameter of the second gear 442 being smaller than the diameter of the first gear 441. At the same time, the driving member 612 is also set as a double gear. Along the first direction, the driving member 612 has a main gear that meshes with the first gear 441 and a secondary gear that is opposite to the second gear 442. During the detection process, the first gear 441 drives the main gear to rotate. When it reaches the detection end of the detection device 6, the first gear 441 disengages from the driving gear, and the second gear 442 begins to mesh with the secondary gear. Since the diameter of the second gear 442 is smaller than the diameter of the first gear 441, the driving member 612 will be accelerated when the second gear 442 drives the secondary gear.

[0132] Example 2

[0133] Based on the above embodiments, this embodiment will modify part of the structure of the transmission component 62. In this embodiment, the same components as in the above embodiments will be numbered the same.

[0134] like Figure 16A and Figure 16B As shown, the transmission member 62 includes a forced push member 620 located at the driving end, a transmission part 623 located at the detection end, and a moving part 622 located between the forced push member 620 and the transmission part 623; an action protrusion 632 is provided on the side of the transmission part 623 near the second rod 92. The action protrusion 632 may be a separately provided component or it may be the end of the transmission part 623 near the second rod 92.

[0135] Furthermore, the forced pusher 620, the moving part 622, and the transmission part 623 are formed separately in pairs. In this embodiment, the transmission part 62 also includes a guide groove 25 disposed on the housing 2. The guide groove 25 is located between a pair of guide plates 252, which protrude upward from the housing 2. In the second direction, the pair of guide plates 252 can be directly opposite each other or staggered. Figure 16A As shown, a pair of guide plates 252 and guide grooves 25 arranged opposite to or spaced apart on the housing 2 cooperate with each other to at least guide or limit the movement trajectory of the transmission part 623. More specifically, the guide plates 252 and guide grooves 25 cooperate with each other to guide the reciprocating movement of the transmission part 623 along the first direction.

[0136] Furthermore, the forced pusher 620 is configured to rotate about the rotation axis L11. Preferably, the rotation axis L11 is not perpendicular to the third direction; more preferably, the rotation axis L11 is parallel to the third direction. When the drive member 612 starts to rotate, the forced pusher 620 is configured to rotate in the direction shown by r8. The moving part 622 is configured to move in the first direction, and the transmission part 623 is configured to move along the guide groove 25 in the first direction. Furthermore, the forced pusher 620 is provided with a central post 6201 and a main body 6202 arranged circumferentially / radially along the central post 6201. The forced push portion 621 protrudes radially from the central post 6201 or axially from the main body 6202 to receive the forced push force. At the same time, a plurality of protrusions 620b arranged adjacent to the forced push portion 621 can be used to receive the driving force to make the forced pusher 620 rotate about the rotation direction r8, thereby driving the moving part 622 and the transmission part 623 to move in the first direction away from the detection end (one end 51 in the first direction), so that the actuating protrusion 632 will not push the first The two rods 92, in this way, can play a delay role; as the forced pusher 620 continues to rotate along the rotation direction r8, when the multiple protrusions 620b no longer receive driving force, the moving part 622 and the transmission part 623 are driven to move in the first direction toward the direction closer to the detection end (the other end 52 of the first direction), and the actuating protrusion 632 pushes the second rod 92 and remains engaged with the second rod 92. Preferably, the forced pusher 620 is set as a toothed gear, so that the part without multiple protrusions 620b does not contact the driving member 612, so that the forced pusher 620 no longer rotates in the direction shown in r8. Subsequently, the reset member 64 will push the transmission member 62 to reset, or as the second rod 92 resets, the second rod 92 pushes the transmission member 62 to reset in turn; as the driving member 612 continues to rotate, the actuating part 4411 of the driving member 612 (such as Figure 13 As shown, the forced push part 620 is combined with the forced push part 621, causing the forced push part 620 to rotate at an angle, thereby driving the moving part 622 and the transmission part 623 to move away from the detection end (the end 51 of the first direction) in the first direction, thereby causing the action protrusion 632 to leave the second rod 92, that is, the second rod 92 is flicked again.

[0137] Furthermore, in this embodiment, a crank-connecting rod structure is formed between the forced pusher 620 and the moving part 622.

[0138] Example 3

[0139] Based on the above embodiments, this embodiment will modify part of the structure of the transmission component 62. In this embodiment, the same components as in the above embodiments will be numbered the same.

[0140] like Figure 17A and Figure 17BAs shown, the transmission member 62 includes a forced push member 620 located at the driving end, a transmission part 623 located at the detection end, and a moving part 622 located between the forced push member 620 and the transmission part 623. The forced push member 620 is configured to rotate about a rotation axis L9, and the transmission part 623 is configured to rotate about a rotation axis L10. Preferably, the rotation axes L9 and L10 are not perpendicular to a third direction. More preferably, the rotation axes L9 of the forced push member 620 and L10 of the transmission part 623 are parallel to a third direction.

[0141] The forced pusher 620 is used to engage with the counter 613. Specifically, the forced pusher 621 is configured to protrude radially from the forced pusher 620 to engage with the counter 613 and receive the forced push force. That is, the forced pusher 620 is driven by the counter 613, or the driving force of the drive member 612 is transmitted to the forced pusher 620 through the counter 613. Thus, the counter 613 can also be referred to as a transition member in the detection device 6. The transition member 613 is configured as a rotating body with partially missing teeth in its circumferential direction. The action protrusion 632 is integrally or separately formed with the transmission part 623. When the transmission part 623 rotates about the rotation axis L10, the action protrusion 632 moves with the transmission part 623, for example, by rotation or translation, to interact with the second rod 92.

[0142] Unlike the above embodiments, in this embodiment, the moving part 622 is configured as a flexible element such as a flexible belt or flexible rope. The flexible element 622 can move back and forth in the first direction. Furthermore, one end of the flexible element 622 is connected to the forced pusher 620, and the other end is connected to the transmission part 623. Preferably, the flexible element 622 does not need to be wrapped around the forced pusher 620 or the transmission part 623. The reset member 67 is used to reset the actuating protrusion 632 for the next detection. Furthermore, the transmission part 623 is provided with a shaft extending axially toward the housing 2. The shaft 623c is used to engage with the housing 2 so that the transmission part 623 can be installed. In this embodiment, the reset member 67 is configured to engage with the transmission part 623. Further, the reset member 67 is a torsion spring. The torsion spring 67 is sleeved on the shaft 623c. The torsion spring 67 has a first end 67a and a second end 67b. The first end 67a abuts against the groove 623d provided in the transmission part 623, and the second end 67b abuts against the housing 2. Further, the groove 623d is formed radially inward from the outer surface 623b of the transmission part 623.

[0143] The forced push part 621 receives the forced push force, causing the forced push member 620 to rotate in the direction shown in r6. This drives the moving part 622 to pull the transmission part 623 to rotate in the direction shown in r7 in the first direction. This causes the actuating protrusion 632 to actuate the second rod 92. At this time, the reset member 67 is squeezed and accumulates reset force. When the forced push part 621 no longer receives the forced push force, the reset force of the reset member 67 causes the transmission part 623 to rotate in the opposite direction to the direction shown in r7. This drives the moving part 622 to pull the forced push member 620 to rotate in the opposite direction to the direction shown in r6 in the first direction. At the same time, the actuating protrusion 632 no longer actuates the second rod 92, and the actuating protrusion 632 resets.

[0144] In this embodiment, a flexible component is used as the moving part 622, which solves the technical problem of excessive load on the stirring rod in the prior art. It also allows for more flexible positioning of the transmission part 623 and the actuating protrusion 632, thus improving the design freedom of the developing cartridge 1. In addition, the flexible component is less prone to breakage and has better stability.

[0145] In other embodiments, the moving part / flexible member 622 can be directly connected to the counting member 613, which simplifies the structure of the transmission member 62.

[0146] Example 4

[0147] In this embodiment, the same components as in the above embodiments are numbered the same.

[0148] like Figure 18 As shown, the transmission member 62 includes a transmission part 623 located at the detection end and a moving part 622 connected to the transmission part 623. The transmission part 623 is configured to rotate about a rotation axis L10. Preferably, the rotation axis L10 is not perpendicular to a third direction; more preferably, the rotation axis L10 of the transmission part 623 is parallel to a third direction. Similar to Embodiment 3, the moving part 622 in this embodiment is also configured as a flexible element such as a flexible belt or flexible rope. In this embodiment, one end of the flexible element 622 is directly connected to the counting member 613, and the other end is connected to the transmission part 623. Moreover, during detection, the flexible element 622 wraps around the counting member 613 and is released by the transmission part 623. In addition, the action protrusion 632 can be configured as one or more according to the detection needs. In this embodiment, three action protrusions 632 are provided, including a first action protrusion 632a, a second action protrusion 632b, and a third action protrusion 632c. Furthermore, the action protrusions 632 are integrally formed with or separate from the transmission part 623.

[0149] During testing, the drive unit 612 drives the counter unit 613 to rotate in the direction shown in r5. The flexible member 622 is pulled and wrapped around the counter unit 613, thereby driving the transmission unit 623 to rotate in the direction shown in r7. This causes the three action protrusions 632 to touch the second rod 92 in sequence. At the same time, the flexible member 622 wrapped around the transmission unit 623 is released.

[0150] It is possible that the counting element 613 in this embodiment is also configured as a rotating body with partially missing teeth in its circumferential direction.

[0151] This embodiment achieves the same technical effects as Embodiment 3, so it will not be described again.

[0152] Example 5

[0153] The above embodiments describe the second forced push part 2b2 being disposed in the housing 2 or the right end cover 28. In some embodiments, the second forced push part 2b2 may also be disposed in other locations, for example, the second forced push part 2b2 may be disposed in the sealing cover 2a4. This design is beneficial to simplifying the structure of the housing 2, and the second forced push part 2b2 can also serve as an operating part for the user to operate the sealing cover 2a4.

[0154] In some embodiments, the second forced pusher 2b2 may also be disposed in a separate component 2i (e.g., Figure 19 As shown, the function of the independent component 2i can be designed according to the design requirements of the developing cartridge 1. For example, a portion of the detection device 6 is supported by the independent component 2i. In this embodiment, the right end cover 28 can be considered as the independent component 2i.

[0155] like Figure 19 As shown, along the first direction, the powder filling port 2a3 is located on the same side as the active component 63; along the third direction, the powder filling port 2a3 does not overlap with the active component 63; along the second direction, the powder filling port 2a3 is located in front of the independent component 2i. This design ensures that the powder filling port 2a3 is directly exposed, allowing the user to replenish developer into the developer chamber 10 without disassembling the components of the developing cartridge. It also reduces the size of the independent component 2i in the front-rear direction, thereby reducing the cost of the independent component 2i and increasing its strength. Preferably, along the third direction, a portion of the independent component 2i overlaps with the active component 63. Continuing as... Figure 19 As shown, when viewed along the first direction, the rotation axis L2 of the drive force receiver 41 / intermediate gear 46 does not pass through the conductive element 26. In this way, the impact of vibration generated by the rotation of the drive force receiver 41 on the electrical contact between the conductive element 26 and the power output element in the imaging device can be reduced, and the stability of the electrical contact can be improved.

[0156] Furthermore, when viewed along the first direction, the power input portion 26b of the conductive member 26 is located outside the projection range of the driving force receiver 41. This design can improve the stability of the electrical contact between the power input portion 26b and the power output member in the imaging device. Furthermore, the power input portion 26b is also located outside the projection range of the intermediate gear 46, thereby further improving the stability of the electrical contact between the power input portion 26b and the power output member in the imaging device.

[0157] In Embodiments 2-5 described above, the driving force is no longer transmitted through the stirring member 33, which can reduce the load on the stirring member 33 and thus prevent the stirring member 33 from breaking. Moreover, the forced pusher and the moving part are formed separately, which can also increase the strength of each component. This can prevent deformation or transmission lag caused by insufficient strength due to the excessive length of a certain component in the first direction. In addition, the use of a more stable flexible component as the moving part can improve the durability and detection accuracy of the detection device.

[0158] Example 6

[0159] Based on the above embodiments, this utility model also provides a developing cartridge without a stirring rack 33, to simplify the structure of the developing cartridge and save costs. Figure 20 As shown, the stirring rack 23 is no longer installed in the developer chamber 10. To ensure that the developer can reach the developing unit 31 and the powder feeding unit 32 smoothly, the lower side plate 2b3 of the lower housing 2b is inclined relative to the second direction. Specifically, the inner surface 2b4 of the lower side plate 2b3 facing the developer chamber 10 is inclined relative to the second direction. Thus, the structure of the developing cartridge 1 can be simplified. When installing and disassembling the developing cartridge 1, the user can directly contact the lower side plate 2b3 with their hands. Compared with the handle 23, the lower side plate 2b3 has a larger area for the user to grip.

[0160] exist Figure 20 In the angle shown, the first straight line P1 passes through the rotation axis L1 of the developing element 31 and the rotation axis L2 of the driving force receiving element 41. The second straight line P2 is parallel to the inner surface 2b3. The first straight line P1 and the second straight line P2 intersect at point P0. The included angle γ formed between them satisfies: 0°<γ≤45°, preferably 5°<γ≤20°.
