[0002] This divisional application is a divisional application of Chinese utility model patent application filed on March 20, 2024, with application number 202420550732.7 and entitled "Developer Box".

[0004] 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

[0005] In the developing cartridge of an imaging device, which is detachably installed, the power output from the device (such as developing bias voltage) typically needs to be transmitted to conductive components such as the developing roller and the toner delivery roller to achieve toner transport and developing functions. In the prior art, rotating components such as the toner delivery roller and the developing roller mostly obtain power through sliding contact between their metal shafts and conductive components. However, during the continuous rotation of the developing component shaft, long-term friction with the conductive components can easily lead to wear, oxidation, or toner accumulation on the contact surface, causing unstable electrical connections, affecting the uniformity of the developing bias voltage, and consequently causing uneven image density, background graying, or printing defects. In addition, to maintain reliable conductivity, it is often necessary to add a flexible pressing structure or surface coating, which increases manufacturing costs and assembly complexity. For high-speed rotating components such as the developing roller, the issue of electrical contact reliability is particularly prominent.

[0006] Therefore, there is an urgent need to provide an improved conductive structure that can avoid direct electrical contact between the developing element shaft and the conductive element, solve the conductivity reliability problem caused by rotational friction, and improve power supply stability.

Detailed Implementation

[0051] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. 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.

[0052] Example 1

[0053] [The overall structure of the developing chamber]

[0054] like Figures 1A-1D , Figure 2 , Figure 3 , Figure 4A and Figure 4BAs shown, the developing cartridge 1 includes a housing 2 forming a developer chamber 10 and a rotating member 3 rotatably mounted 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. The developing member 31 and the handle 23 are located at opposite ends of the housing 2 along the installation direction.

[0055] The developing element 31 rotates around 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 intersecting the first direction and a third direction intersecting both the first and second directions. Preferably, the first, second, and third directions are perpendicular to each other. 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, where the developing element 31 is located in front of the developing cartridge. The other end 54 of the second direction points to the rear of the developing cartridge, and the side opposite to the side where the developing element 31 is located is 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.

[0056] 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 testing end. The developing cartridge 1 also includes a testing device 6, which has a portion located at the driving end, another portion at the testing end, and a portion located between the driving end and the testing 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 testing device 6.

[0057] 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 conductive member 26 is located at the detection end and is used to receive power from the device to the developing member 31.

[0058] When the developing cartridge 1 is working, the developing element 31 needs to be aligned with the photosensitive element outside the developing cartridge so that the developer on the surface of the developing element 31 can reach 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 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 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.

[0059] [Right end cap]

[0060] 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.

[0061] [Guideboard]

[0062] 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.

[0063] In practice, to prevent developer leakage, such as Figure 1B As shown, along the first direction, the developing cartridge 1 also includes first sealing members 39 located at the two longitudinal ends of the developing member 31, and as shown in the figure. Figure 3 As shown, along the second direction, the developing cartridge also includes at least a portion of a second seal 38 and a third seal 37 located in front of the developing element 13. The first seal 39 is preferably felt / sponge for sealing the longitudinal end of the developing element 31. The second seal 38 is preferably a sheet seal for contacting and sealing the circumferential surface of the developing element 31. The third seal 37 is preferably a sponge for contacting and sealing the circumferential surface of the developing element 31.

[0064] In existing systems, the first seal 39, second seal 38, and third seal 37 are all attached to the housing 2 by applying double-sided adhesive to one side. This method is disadvantageous for automated production, and the first seal 37, located at the two longitudinal ends of the developing element, will be subjected to significant tensile force, potentially causing it to tear open. Furthermore, this method results in low installation precision and poor sealing performance. This invention achieves precise attachment between the first seal 39 / second seal 38 and the housing 2 by injecting adhesive onto the side of the first seal 39 / second seal 38 facing the housing. Figure 1CAs shown, two injection ports 2e are also provided below the housing 2. Each injection port 2e is connected to at least one of the first seal 39 and the second seal 38. In this way, the adhesive injected through the injection port 2e can smoothly reach the side of the first seal 39 and / or the second seal 38 facing the housing 2. Injecting adhesive through the injection port 2e not only increases the bonding strength between the seal and the housing 2, but also effectively fills the gaps between the first seal 39, the second seal 38, and the third seal 37, as well as the gaps between the seals and the housing 2. In addition, injecting adhesive through the injection port 2e can also enable automated production of the developing cartridge 1. Preferably, along the first direction, the guide plate 2e is located between the two injection ports 2e to avoid the guide plate 2d from blocking the injection ports 2e. Further, along the first direction, the guide plate 2e is located between the conductive element 26 and the chip assembly 11 to avoid the chip assembly 11 being affected by the conductive element 26.

[0065] [Drive force transmission components]

[0066] The driving force transmission assembly 4 includes at least one of a driving force receiving component 41, a developing component driving component 42, a powder feeding component driving component 43, and a stirring component driving component 44. When a stirring component driving component 44 is provided, the driving force transmission assembly 4 also includes an idler wheel 45 located between the driving force receiving component 41 and the detection device 6. The driving force receiving component 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.

[0067] 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.

[0068] [Detection Device]

[0069] 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.

[0070] Example 2

[0071] like Figure 5 , Figure 6 , Figure 7A , Figure 7B and Figure 8 As shown, based on the above embodiments, this embodiment focuses on describing the structure of the conductive element 26 and its relative position in the developing cartridge.

[0072] like Figure 5 As shown, along the second direction (the installation and removal direction of the developing cartridge 1), the imaging device is provided with a first power output component 101 and a second power output component 102 spaced apart from each other. In the existing developing cartridge, the first power output component 101 is used to supply power to the powder feeding component 32, and the second power output component 102 is used to supply power to the developing component 31. In the forward direction (the front 53 of the developing cartridge), the second power output component 102 is located downstream of the first power output component 101.

[0073] In order to ensure that the developing cartridge 1 can receive power stably, this embodiment adopts a method in which the first power output unit 101 simultaneously supplies power to the developing unit 31 and the powder feeding unit 32. As shown in the figure, the conductive element 26 includes a main body 26a and a power input part 26b, a developing element power supply part 26c, and a powder feeding element power supply part 26d disposed on the main body 26a. The conductive element 26 is fixedly connected to the housing 2. In practice, the conductive element 26 can be fixedly connected to the housing 2 through at least any part of it. For example, the main body 26a is fixedly connected to the housing 2, or the power input part 26b is fixedly connected to the housing 2, or the developing element power supply part 26c is fixedly connected to the housing 2, or the powder feeding element power supply part 26d is fixedly connected to the housing 2. The power input part 26b is used to be electrically connected to the first power output part 101 to receive power. The developing element power supply part 26c is used to supply the power received by the power input part 26b to the developing element 31, and the powder feeding element power supply part 26d is used to supply the power received by the power input part 26b to the powder feeding element 32.

[0074] In some embodiments, the conductive element 26 is integrally formed of a conductive material. For example, the conductive element 26 can be integrally injection molded from conductive plastic or integrally pressed from a conductive metal sheet.

[0075] In some embodiments, the conductive component 26 is formed separately. The power input section 26b, the developing component power supply section 26c, and the powder feeding component power supply section 26d are made of the aforementioned conductive material. The power input section 26b is electrically connected to both the developing component power supply section 26c and the powder feeding component power supply section 26d via conductive connectors. In this way, the power received by the power input section 26b can be simultaneously supplied to the developing component power supply section 26c and the powder feeding component power supply section 26d, and then supplied by the developing component power supply section 26c and the powder feeding component power supply section 26d to the developing component 31 and the powder feeding component 32, respectively. Preferably, the main body 26a is made of conductive material. As a result, the installation of conductive connectors can be omitted, and defects in conductivity caused by assembly errors or material deformation between the components of the conductive component 26 can be avoided.

[0076] like Figure 6 As shown, the power supply unit 26c of the developing element supplies power to the developing element 31 by being electrically connected to the developing element shaft 311 of the developing element 31, and the power supply unit 26d of the powder feeding element supplies power to the powder feeding element 32 by being electrically connected to the powder feeding element shaft 321 of the powder feeding element 32. The electrical connection can be direct contact or indirect contact, and can be contacting the circumferential surface of the developing element shaft 311 / powder feeding element shaft 321 or contacting the longitudinal end of the developing element shaft 311 / powder feeding element shaft 321.

[0077] like Figure 7AAs shown, when the developing cartridge 1 reaches the predetermined installation position of the imaging device, along the first direction, the first power output component 101 contacts the conductive component 26 / power input portion 26b at point D, but the second power output component 102 is not electrically connected to the conductive component 26. Along the first direction, the developing component power supply portion 26c has a first exposed surface 26c1 facing to the right 52. Preferably, the first exposed surface 26c1 is set to be inclined relative to the second direction, and along the second direction, the first exposed surface 26c1 gradually moves away from the housing 2 from the front to the rear. This design makes it easier for the developing cartridge 1 to be installed into the imaging device.

[0078] like Figure 8 As shown, along the first direction, the power input section 26b also has a second exposed surface 26b1 facing to the right 52. The second exposed surface 26b1 is set as a plane and is used to contact the first power output component 101 at point D. As a deformation mode of the conductive component 26, the second exposed surface 26b1 can also be set to be inclined relative to the second direction. Along the second direction, the second exposed surface 26b1 gradually moves away from the housing 2 from the front to the rear. Similarly, this design can make it easier to install the developing cartridge 1 into the imaging device and can prevent the first power output component 101 and the conductive component 26 from interfering with each other and causing damage to both.

[0079] As described above, the actuating component 63 for moving the object 9 in the imaging device is exposed towards the detection end. The actuating component 63 can move the object 9 by rotation or translation. The transmission component 62 for driving the actuating component 63 can also move by rotation or translation.

[0080] like Figure 7B As shown, when observing the developing cartridge 1 along the first direction, draw a straight line N parallel to the second direction. Along the third direction, the projection points of the rotation axis L1 of the developing element 31, the contact point D, and the free end of the actuating component 63 on the straight line N are T1, T2, and T3, respectively. Along the second direction, the distance between points T1 and T2 is s1, and the distance between points T2 and T3 is s3, where s1 > s3. That is, the contact point D is closer to the free end of the actuating component 63. As a result, the influence of the vibration of the developing element 31 on the contact point D is reduced. In other words, the first power output component 101 can stably output power to the power input unit 26b.

[0081] It should be noted that the free end of the actuating component 63 refers to the part of the actuating component 63 used to move the tested part 9 to complete the test.

[0082] When the transmission member 62 drives the actuating component 63 by rotation, the rotation axis L6 of the transmission member 62 intersects the straight line N at point T4. Along the second direction, the distance between points T2 and T4 is s2, where s1 > s2. That is, the contact point D is closer to the free end of the actuating component 63, thereby reducing the impact of the vibration of the developing element 31 on the contact point D. When the transmission member 62 drives the actuating component 63 by translation, the point T4 is the projection of the midpoint of the dimension of the transmission member 62 in the second direction onto the straight line N.

[0083] During the operation of the developing chamber, compared to the vibration generated by the interaction force between the developing element 31 and the photosensitive drum, the vibration that the transmission element 62 and the action component 63 may generate is smaller because the transmission element 62 and the action component 63 only need to move the detected element 9. In the second direction, the contact point D is closer to the action component 63 / transmission element 62, which is more conducive to ensuring a stable power output from the first power output element 101 to the power input part 26b.

[0084] Accordingly, this embodiment can achieve the following beneficial effects:

[0085] 1. Along the second direction, compared to the distance between the contact point D of the first power output component 101 and the conductive component 26 and the actuating component 63 / transmission component 62, the distance between the contact point D of the first power output component 101 and the conductive component 26 and the rotation axis L1 of the developing component 31 is larger. This is beneficial to reduce the impact of vibration of the developing component 31 and make the electrical connection between the first power output component 101 and the conductive component 26 / power input part 26b more stable.

[0086] 2. As described above, the developer 31 delivers developer to the photosensitive drum. During this process, a small amount of developer will drift away from the developer 31 and the photosensitive drum. Therefore, in point 1, the arrangement away from the developer 31 can also reduce the risk of developer drifting to the power input section 26b, thereby reducing the impact of developer on the electrical connection between the first power output section 101 and the conductive section 26 / power input section 26b, and ensuring that the conductive section 26 / power input section 26b receives power stably.

[0087] 3. Along the first direction, the conductive element 26 is located at the detection end rather than at the driving end. When the developing cartridge is working, the vibration generated by the driving force transmission component 4 located at the driving end has less impact on the electrical connection between the first power output component 101 and the conductive element 26.

[0088] 4. Based on point 3, no transmission gear is provided at the detection end, so that the first power output component 101 and the conductive component 26 can be electrically connected more stably.

[0089] 5. For example Figure 7BAs shown, when viewed along the first direction, the second power output device 102 is located within the projection range of the driving force receiver 41 at the detection end, while the first power output device 101 is located outside the projection range. It can be seen that the driving force receiver 41 has a smaller impact on the electrical connection between the first power output device 101 and the power input device 26 when it is working.

[0090] 6. As described above, the powder feeding member 32 is used to supply developer to the developing member 31. Generally, the voltage applied to the powder feeding member 32 is higher than the voltage applied to the developing member 31. That is, the voltage output by the first power output member 101 is higher than the voltage output by the second power output member 102. When the conductive member 26 receives the power output by the first power output member 101, the voltage required by the powder feeding member 32 can be guaranteed. Even if there is impedance in the main body 26a or the conductive connector, the voltage delivered to the developing member 31 can meet the developing requirements of the developing member 31.

[0091] Accordingly, a step-down element can be provided between the power input section 26b and the power supply section 26c of the developing element to ensure that the developing element 31 can receive a suitable voltage.

[0092] Conversely, when the conductive element 26 receives the power output from the second power output element 102, since the voltage originally output by the second power output element 102 is lower than the voltage required by the powder feeding element 32, and the impedance of the main body 26a or the conductive connector is added, the voltage received by the powder feeding element 32 will be even lower, which will be detrimental to the normal operation of the powder feeding element 32. In this method, although the powder feeding element 32 can obtain a suitable voltage by setting a boost element in the conductive element, obviously, the cost of the step-down element is lower and it is easier to install.

[0093] Example 3

[0094] like Figure 9 As shown, for ease of understanding and explanation, the same components as those in the above embodiments will be numbered the same.

[0095] The conductive element 26 still includes a main body 26a and a power input part 26b and a developing element power supply part 26c disposed on the main body 26a. The conductive element 26 is fixedly connected to the housing 2. The power input part 26b is used to be electrically connected to the first power output part 101 to receive power. The developing element power supply part 26c is used to supply the power received by the power input part 26b to the developing element 31. Specifically, the developing element power supply part 26c is electrically connected to the developing element shaft 311 to supply power to the developing element 31. In this embodiment, the powder feeding part 32 is not directly supplied with power, that is, the powder feeding part 32 is not in electrical contact with the conductive element 26. Therefore, the conductive element 26 does not need to be provided with the aforementioned powder feeding part power supply part 26d for being electrically connected to the powder feeding part shaft 321. Finally, the structure of the conductive element 26 is simplified.

[0096] Furthermore, continuing as Figure 9 As shown, the powder feeding component 32 is located inside the housing 2. In the left-right direction, the powder feeding component 32 does not extend beyond the right surface 22 of the housing 2. In this way, the conductive component 26 will not be electrically connected to the powder feeding component 32 / powder feeding component shaft 321. In some embodiments, the powder feeding component 32 may also be configured to pass through the right surface 22, but the conductive component 26 is still not electrically connected to the powder feeding component 32 / powder feeding component shaft 321.

[0097] As described above, since the voltage output by the first power output unit 101 is higher than the voltage output by the second power output unit 102, when the conductive element 26 receives power from the first power output unit 101, even if the developing cartridge 1 is in a harsh environment and the charging performance of the developer decreases, the developing element 31 can obtain a higher voltage. A larger electric field force can be generated between the developing element 31 and the photosensitive drum. As a result, the developer can smoothly reach the surface of the photosensitive drum from the surface of the developing element 31, and the deterioration of the developing quality can be effectively suppressed.

[0098] Based on the inventive concept described in this utility model embodiment, without changing the voltage received by the developing element 31, the physicochemical characteristics of the developer can be changed to improve the charging performance of the developer, thereby enabling the developer to smoothly reach the surface of the photosensitive drum from the surface of the developing element 31.

[0099] Similar to Embodiment 2, the power input section 26b in this embodiment also has the second exposed surface 26b1, and the second exposed surface 26b1 can also be set to be inclined relative to the second direction. Along the second direction, the second exposed surface 26b1 gradually moves away from the housing 2 from the front to the rear, which can also prevent the first power output component 101 and the conductive component 26 from interfering with each other and causing damage to both.

[0100] Example 4

[0101] like Figure 10 As shown, for ease of understanding and explanation, the same components as those in the above embodiments will be numbered the same.

[0102] The agitator 33 is configured to reciprocate in a direction substantially parallel to the second direction, as shown in the figure. The agitator 33 includes a frame 331 and a powder feeding plate 332 disposed on the frame 331. The frame 331 is connected to the housing 2 via an elastic member 16. As the drive rod 89 rotates, the frame 331 is pushed by the force applied by the force-applying part 893 (e.g., a cam) disposed on the drive rod 89 and moves substantially in the second direction away from the developing element 31 (towards the handle 23). The elastic member 16 undergoes elastic deformation and accumulates elastic force. When the force-applying part 893 no longer applies force to the frame 331, the elastic member 16 releases the elastic force, causing the frame 331 to move substantially in the second direction towards the developing element 31 (away from the handle 23). When the agitator 33 collides with the drive rod 89, the powder feeding plate 332 will vibrate, and the developer located above the powder feeding plate 332 will fall. The powder feeding plate 332 will transport the developer away from the developing element 31 towards the developing element 31.

[0103] Furthermore, the developing cartridge 1 also includes a buffer 34 disposed on the stirring member 33. When the buffer 34 moves toward the developing member 31 along with the stirring member 33, the noise generated when the buffer 34 collides with the drive rod 89 can be reduced. Preferably, along the second direction, the buffer 34 is opposite to the force-applying part 893. In this way, when the force-applying part 893 applies a pushing force to the stirring member 33, the noise of the collision between the force-applying part 893 and the stirring member 33 can also be reduced. At the same time, the abnormal noise generated when the stirring member 33 shakes can also be reduced.

[0104] It is feasible that the buffer 34 can be combined with the stirring component 33 by means of pasting, welding, snap-fitting, etc. The buffer 34 is preferably an elastic component, for example, at least a part of the buffer 34 is made of sponge, silicone, spring, etc.

[0105] like Figure 10 As shown, more preferably, the buffer 34 is connected to the stirring member 33 by a snap-fit ​​method. The frame 331 is provided with a mounting part 333, and at least a part of the buffer 34 is accommodated by the mounting part 333. For example, the buffer 34 is provided with a snap-fit ​​groove 341, and correspondingly, the mounting part 333 is provided with a snap-fit ​​protrusion 334 that cooperates with the snap-fit ​​groove 341. At the same time, the buffer surface 342 of the buffer 34 faces the drive rod 89.

[0106] In addition, compared to the method of attaching the buffer 34 to the stirring member 33, the method of engaging the locking groove 341 and the locking protrusion 334 can ensure that the buffer 34 is installed more conveniently and stably, and the installation position of the buffer 34 can be precisely controlled.

[0107] Example 5

[0108] like Figure 11 and Figure 12 As shown, in this embodiment, the conductive element 26 still includes a main body 26a and a power input part 26b and a powder feeding part power supply part 26d disposed on the main body 26a. The conductive element 26 is fixedly connected to the housing 2. The power input part 26b is used to be electrically connected to the first power output part 101 or the second power output part 102 to receive power. The powder feeding part power supply part 26d is used to supply the power received by the power input part 26b to the powder feeding part 32. Specifically, the powder feeding part power supply part 26d is electrically connected to the powder feeding part shaft 321 to supply power to the powder feeding part 32. In this embodiment, the developing... The developing element 31 is not directly supplied with power, meaning that the developing element 31 does not need to be directly electrically connected / in contact with the first power output element 101 or the second power output element 102. Instead, it is powered by the powder feeding element 32. Therefore, the conductive element 26 does not need to be provided with the aforementioned developing element power supply section 26c for electrical connection with the developing element shaft 311. Finally, the structure of the conductive element 26 is simplified. In some embodiments, the developing element shaft 311 can also be made of a non-conductive material. Even if a conductive component (e.g., the conductive element 26) is in contact with the developing element shaft 311, the developing element shaft 311 will not transmit power to the developing layer 312.

[0109] like Figure 11 As shown, the powder feeding shaft 321 is exposed from the right surface 22 of the housing, and the developing element 31 is located inside the housing 2. In the left-right direction, the developing element 31 does not extend beyond the right surface 22 of the housing 2, so that the conductive element 26 is not electrically connected to the developing element 31 / developing element shaft 311. In some embodiments, the developing element 31 may also be configured to pass through the right surface 22, but the conductive element 26 is still not electrically connected to the developing element 31 / developing element shaft 311.

[0110] like Figure 3As shown, the developing element 31 further includes a developing layer 312, and the powder feeding element 32 further includes a powder feeding layer 322. The developing layer 312 is further away from the developing element's rotation axis L1 than the circumferential surface of the developing element shaft 311, and the powder feeding layer 322 is further away from the powder feeding element's rotation axis L7 than the circumferential surface of the powder feeding element shaft 321. The developing layer 312 and the powder feeding layer 322 are in contact with each other. Generally, both the developing layer 312 and the powder feeding layer 322 are made of elastic materials. In this embodiment, when the developing element 31 is not directly powered, the powder feeding layer 322 and the developing layer 312 are preferably made of elastic conductive materials. For example, the powder feeding layer 322 and the developing layer 312 are made of conductive sponge / rubber, etc. In this way, after the powder feeding element 32 is powered, an electric field force will be formed between the surface of the powder feeding element 32 and the surface of the developing element 31. The developer on the surface of the powder feeding element 32 can reach the surface of the developing element 31 under the action of the electric field force. At the same time, the power supplied to the powder feeding element 32 will be transferred to the developing layer 312 through the powder feeding layer 322. As a result, the developing element 31 is also powered. Subsequently, the developer adjusting element 29 that is in contact with the surface of the developing element 31 / developing layer 312 is also powered.

[0111] Furthermore, when the powder feeding component 32 is powered, the developer on the surface of the powder feeding component 32 will also be charged, thereby forming an electric field between the developer on the surface of the powder feeding component 32 and the surface of the developing component 31. Under the action of this electric field, the developer can more easily reach the surface of the developing component 31 from the surface of the powder feeding component 32.

[0112] As can be seen, in this embodiment, not only can the powder feeding layer 322 serve as a component that supplies power to the developing element 31, but the developer located between the developing element 31 and the powder feeding layer 32 can also serve as a component that supplies power to the developing element 31.

[0113] Based on the inventive concept of this utility model embodiment, the developing element 31 and the powder feeding element 32 can be either of the following two specific structures:

[0114] In some embodiments, along a first direction, the developing element shaft 311 passes through the developing layer 312, and the powder feeding element shaft 321 passes through the powder feeding layer 322. At this time, the developing layer 312 covers at least a portion of the circumferential surface of the developing element shaft 311, and the powder feeding layer 322 covers at least a portion of the circumferential surface of the powder feeding element shaft 321.

[0115] In some embodiments, along the first direction, the developing element shaft 311 does not pass through the developing layer 312, and the powder feeding element shaft 321 does not pass through the powder feeding layer 322. In this case, the developing layer 312 covers a portion of the circumferential surface of the developing element shaft 311, or the developing layer 312 does not cover the circumferential surface of the developing element shaft 311, and the developing element shaft 311 protrudes from the longitudinal end face of the developing layer 312. The powder feeding layer 322 covers a portion of the circumferential surface of the developing element shaft 321, or the powder feeding layer 322 does not cover the circumferential surface of the powder feeding element shaft 321, and the powder feeding element shaft 321 protrudes from the longitudinal end face of the powder feeding layer 322.

[0116] In particular, when the power input unit 26b is electrically connected to the first power output unit 101, the developing unit 31 will be able to receive a voltage higher than the predetermined voltage. Even if the processing cartridge 1 is in a humid, high temperature and high pressure environment, the charge of the developer reaching the surface of the developing unit 31 can be kept within a reasonable range. As a result, the deterioration of the developing quality of the processing cartridge 1 can be effectively suppressed.

[0117] Similar to the above embodiments, such as Figure 12 As shown, the power input section 26b has a second exposed surface 26b1 facing to the right 52. The second exposed surface 26b1 is formed as a plane for contacting the first power output member 101 / second power output member 102 at point D. Preferably, the second exposed surface 26b1 is set to be inclined relative to the second direction. Along the second direction, the second exposed surface 26b1 gradually moves away from the housing 2 from the front to the rear. Similarly, this design also makes it easier to install the developing cartridge 1 into the imaging device and prevents the first power output member 101 and the conductive member 26 from interfering with each other and causing damage to both.

[0118] Example 6

[0119] First refer to Figure 3 As shown, the developer adjustment member 29 includes a fixed body 291 fixedly connected to the housing 2 and an adjustment body 292 disposed on the fixed body 291. The adjustment body 292 is in contact with the developing layer 312. In some embodiments, both the adjustment body 292 and the developing layer 312 are made of conductive material. Therefore, it is possible to power the developing member 31 using the developer adjustment member 29. This solution will be described in detail below.

[0120] like Figure 13 , Figure 14 , Figures 14A-14CAs shown, the conductive element 26 includes a main body 26a and a power input part 26b and an adjustment power supply part 26e disposed on the main body 26a. The power input part 26b is used to receive power by being electrically connected to the second power output part 102. The developing element 31 and the powder feeding element 32 are not directly electrically connected to the conductive element 26, that is, the developing element 31 and the powder feeding element 32 are not in direct electrical contact with the conductive element 26.

[0121] Specifically, the power supply unit 26e of the adjustment member is configured to be in direct electrical contact with at least one of the fixed body 291 and the adjustment body 292. In this way, the power received by the power input unit 26b can be supplied to the developer adjustment member 29 through the power supply unit 26e of the adjustment member. Along the first direction, the adjustment body 292 is in contact with the developing layer 312. Therefore, the developer member 31 receives power from the developer adjustment member 29 through the developing layer 312 or the developer carried by the developing layer 312. Subsequently, the developer member 31 transmits the power to the powder feeding member 32 in contact with it.

[0122] like Figure 14 As shown, the power input section 26b also has the second exposed surface 26b1 that is inclined relative to the second direction, which will not be described again here; it should be noted that in this embodiment, the developing element 31 no longer receives power through the developing element shaft 311 and the conductive element 26 in an electrical connection, but receives power from the developer conditioning element 29 through the developing layer 312. During the operation of the developing cartridge 1, even if the developing element 31 rotates continuously, there is no need to worry about friction between the developing element shaft 311 and the conductive element 26 causing the electrical connection between the two to become unstable.

[0123] Meanwhile, the developing element 31 / developing layer 311 receives power from the developer conditioning element 29, and the position where the developing element conditioning element 29 contacts the developing element 31 / developing layer 311 is far away from the position where the developing element 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing element and the photosensitive drum, the developing element 31 can still receive power stably.

[0124] As described above, the conductive element 26 in this embodiment does not require the aforementioned power supply unit 26c for the developing element and power supply unit 26d for the powder feeding element, thus simplifying the structure of the conductive element 26.

[0125] In addition, compared to the conductive method in which the conductive element 26 contacts the end of the developing element shaft 311, in this embodiment, the adjusting body 292 contacts the developing layer 312 / developing element 31 along the first direction, the electrical contact surface of the developing layer 312 / developing element 31 is increased, and correspondingly, the electrical connection stability of the developing element 31 is improved, and a uniform voltage can be obtained on the surface of the developing element 31 / developing layer 311.

[0126] Furthermore, such as Figure 14AAs shown, along the first direction, the outer surface of the developing element 31 / developing layer 311 has two non-developing regions X1 arranged opposite to each other and a developing region X2 located between the two non-developing regions X1, and the adjusting body 292 is in contact with at least the developing region X2.

[0127] To achieve a more uniform voltage on the surface of the developing element 31 / developing layer 311, the developing element 31 also includes a power enhancement element 35 disposed in the developing element 31 / developing layer 311. The power enhancement element 35 is a conductor, and the power enhancement element 35 can extend either on the outer surface of the developing element 31 / developing layer 311 or in the developing layer 311.

[0128] Figure 14A A first type of power enhancement element 35A is shown, which extends in a non-linear manner in a first direction. Specifically, the first type of power enhancement element 35A is configured to extend in a wavy manner in the first direction. When the developer conditioning element 29 and / or the powder feeding element 32 below come into contact with the power enhancement element 35A, the power enhancement element 35A can uniformly apply voltage to the outer surface of the developer element 31 / developer layer 311.

[0129] When the developing element 31 is projected along the first direction, the power enhancement element 35 is a circle formed on the developing element 31 / developing layer 311, and the rotation axis L1 of the developing element passes through the center of this circle.

[0130] Figure 14B A second type of power enhancement element 35B is shown. The second type of power enhancement element 35B extends linearly in a first direction. Multiple second type of power enhancement elements 35B are arranged parallel to each other on the outer surface of the developing element 31 / developing layer 311. When the developer conditioning element 29 and / or the powder feeding element 32 described below come into contact with the power enhancement element 35B, the power enhancement element 35B can uniformly apply voltage to the outer surface of the developing element 31 / developing layer 311.

[0131] When the developing element 31 is projected along the first direction, the power enhancement element 35 is a point formed on the developing element 31 / developing layer 311.

[0132] Figure 14C A third type of power enhancement element 35C is shown, which extends in a mesh-like pattern in a first direction. When the developer conditioning element 29 and / or the powder feeding element 32 described below come into contact with the power enhancement element 35C, the power enhancement element 35C can uniformly apply voltage to the outer surface of the developer element 31 / developer layer 311.

[0133] When the developing element 31 is projected along the first direction, the power enhancement element 35 is a circle formed on the developing element 31 / developing layer 311, and the rotation axis L1 of the developing element passes through the center of this circle.

[0134] In the first type of power enhancement element 35A and the third type of power enhancement element 35C, when the developing element 31 is projected along the first direction, the power enhancement element 35A / 35C can also be an arc formed on the developing element 31 / developing layer 311. That is, the projection of the power enhancement element 35A / 35C in the first direction is not a complete circle, and the rotation axis L1 of the developing element passes through the center of the circle where the arc is located. However, as long as the power enhancement element 35A / 35C can contact the developer conditioning element 29 and / or the powder feeding element 32 described below, the voltage can be uniformly applied to the outer surface of the developing element 31 / developing layer 311.

[0135] Example 7

[0136] like Figure 15 and Figure 16 As shown, unlike Embodiment Six, in this embodiment, the developer adjustment member 29 and the powder feeding member 32 are simultaneously in electrical contact with the conductive member 26. For example, the fixing body 291 / adjusting body 292 is in direct electrical contact with the conductive member 26, and the powder feeding member shaft 322 is in direct electrical contact with the conductive member 26. Figure 15 As shown, the conductive element 26 includes a main body 26a and a power input part 26b, an adjustment element power supply part 26e, and a powder feeding element power supply part 26d disposed on the main body 26a; the power input part 26b is electrically connected to the second power output part 102 to receive power, and the adjustment element power supply part 26e and the powder feeding element power supply part 26d supply power to the developer adjustment part 29 and the powder feeding part 32, respectively.

[0137] Along the first direction, the developer conditioning member 29 is in contact with the developing layer 312, and at the same time, the powder feeding member 32 / powder feeding layer is also in contact with the developing layer 312. Therefore, at least one of the power received by the developer conditioning member 29 and the power received by the powder feeding member 32 is supplied to the developing layer 312.

[0138] In this embodiment, the power input section 26b also has the second exposed surface 26b1 that is inclined relative to the second direction. The developing element 31 does not need to directly contact the conductive element 26 through the developing element shaft 311 to receive power. That is, the developing element 31 does not directly contact the conductive element 26. During the operation of the developing cartridge 1, even if the developing element 31 rotates continuously, there is no need to worry about friction between the developing element shaft 311 and the conductive element 26, which would cause the electrical connection between the two to become unstable.

[0139] Meanwhile, the developing element 31 / developing layer 311 receives power from at least one of the developer conditioning element 29 and the powder feeding element 32. The positions where the developer conditioning element 29 contacts the developing element 31 / developing layer 311 and the positions where the powder feeding element 32 contacts the developing element 31 / developing layer 311 are far away from the positions where the developing element 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing element and the photosensitive drum, the developing element 31 can still receive power stably.

[0140] Example 8

[0141] like Figure 17 and Figure 18 As shown, unlike Embodiment Six, in this embodiment, the conductive element 26 is electrically connected to the first power output element 101 to receive power, and the developing element 31 and the powder feeding element 32 are not directly electrically connected to the conductive element 26. That is, the developing element 31 and the powder feeding element 32 are not in direct electrical contact with the conductive element 26. The conductive element 26 is in direct electrical contact with the fixing body 291 / adjusting body 292. In this way, the conductive element 26 will receive power and supply it to the developer adjusting element 29. Similar to Embodiment Six, the developer adjusting element 29 will then supply power to the developing element 31 / developing layer 312, and finally the developing element 31 / developing layer 312 will supply power to the powder feeding element 32 / powder feeding layer 322.

[0142] Similarly, the power input section 26b in this embodiment also has the second exposed surface 26b1 that is inclined relative to the second direction. The developing element 31 does not need to directly contact the conductive element 26 through the developing element shaft 311 to receive power. During the operation of the developing cartridge 1, even if the developing element 31 rotates continuously, there is no need to worry about friction between the developing element shaft 311 and the conductive element 26, which would cause the electrical connection between the two to become unstable.

[0143] Similar to Embodiment Six, the developing element 31 / developing layer 311 receives power from the developer conditioning element 29, and the position where the developing element conditioning element 29 contacts the developing element 31 / developing layer 311 is far away from the position where the developing element 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing element and the photosensitive drum, the developing element 31 can still receive power stably.

[0144] Example 9

[0145] like Figure 19 and Figure 20As shown, unlike Embodiment 7, in this embodiment, the conductive element 26 is electrically connected to the first power output element 101 to receive power, and the conductive element 26 directly transmits the received power to the developer adjustment element 29 and the powder feeding element 32. Finally, the developer adjustment element 29 and / or the powder feeding element 32 supply power to the developing layer 312 / developing element 31. For example, the fixing body 291 / adjusting body 292 is in direct electrical contact with the conductive element 26, and the powder feeding element shaft 322 is in direct electrical contact with the conductive element 26. In this way, the developing element 31 does not need to receive power through direct contact between the developing element shaft 311 and the conductive element 26. That is, the developing element 31 and the conductive element 26 are not in direct electrical contact. During the operation of the developing cartridge 1, even if the developing element 31 rotates continuously, there is no need to worry about friction between the developing element shaft 311 and the conductive element 26 causing the electrical connection between them to become unstable.

[0146] Similar to Embodiment 7, the developing element 31 / developing layer 311 receives power from at least one of the developer conditioning element 29 and the powder feeding element 32. The positions where the developer conditioning element 29 contacts the developing element 31 / developing layer 311 and the positions where the powder feeding element 32 contacts the developing element 31 / developing layer 311 are far away from the positions where the developing element 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing element and the photosensitive drum, the developing element 31 can still receive power stably.

[0147] Example 10

[0148] like Figure 21 As shown, this embodiment further provides a structure for supplying power to the rotating component 3, such as... Figure 21 As shown, the conductive element 26 in this embodiment includes a developing element power input section 26b2, a powder feeding element power input section 26b3, and a power output section 26e. The developing element power input section 26b2 is used to connect with the second power output section 102 to receive the power output by the second power output section 102. The powder feeding element power input section 26b3 is used to connect with the first power output section 101 to receive the power output by the first power output section 101. The power output section 26e is used to simultaneously supply the power received by the developing element power input section 26b2 and the power received by the powder feeding element power input section 26b3 to any one of the developing element 31, the powder feeding element 32, and the developer adjusting element 29. When the power output by the power output section 26e is supplied to the powder feeding element 32 or the developer adjusting element 29, the powder feeding element 32 or the developer adjusting element 29 then supplies power to the developing element 31.

[0149] In a modifiable configuration, the power output unit 26e can also be used to simultaneously supply the power received by the developing unit power input unit 26b2 and the power received by the powder feeding unit power input unit 26b3 to at least one of the developing unit 31, the powder feeding unit 32, and the developer conditioning unit 29.

[0150] This power supply method has the following beneficial effects:

[0151] 1. In this solution, the power output by the first power output unit 101 and the power output by the second power output unit 102 are simultaneously received by the conductive element 26 and output by the conductive element 26 to any one of the developing element 31, the powder feeding element 32, and the developer adjusting element 29. Compared with the solution where the first power output unit 101 or the second power output unit 102 is in contact with the conductive element 26, the current output by the conductive element 26 in this solution is larger. Consequently, the power obtained by the developing element 31, the powder feeding element 32, or the developer adjusting element 29 is also greater, which can ensure that the developing quality is maintained well.

[0152] 2. Compared to the conductive element 26 outputting power to the developing element 31, when the conductive element 26 outputs power to the developer conditioning element 29 or the powder feeding element 32, the power output part 26e is further away from the contact position between the developing element 31 and the photosensitive element along the second direction. Therefore, during the operation of the developing cartridge 1, the vibration generated between the developing element 31 and the photosensitive element has a smaller impact on the power output part 26e.

[0153] 3. Compared to the conductive element 26 being in direct contact with the developing element shaft 311, when the conductive element 26 outputs power to the developer conditioning element 29 or the powder feeding element 32, since both the developing element 32 and the developer conditioning element 29 are in direct contact with the outer surface of the developing element 31, the power output by the powder feeding element 32 or the power output by the developer conditioning element 29 can be directly transmitted to the developing element 31, resulting in less power loss.

[0154] The developing cartridge 1 also includes a right support 2g for supporting the developing element 31. The conductive element 26 can be integrally formed with the right support 2g or formed separately. Figure 21 The structure formed by the conductive element 26 and the right support 2g is shown.

[0155] Example 11

[0156] like Figure 22-24B As shown, based on the above embodiments, this embodiment further describes the chip component 11, which is the same as in Embodiment 1, such as... Figure 22 and Figure 23 As shown, the chip assembly 11 in this embodiment also includes a conductor A92, a pusher A93, a movable member A94, and a chip 7. The working process of each component in the chip assembly 11 is the same as that in Embodiment 1, and will not be repeated here. The conductor A92, the pusher A93, and the movable member A94 form at least a part of the chip communication assembly. Preferably, the chip assembly 11 also includes a pressing member A98 for preventing the conductor A92 from falling off.

[0157] Unlike Embodiment 1, the chip assembly 11 is disposed on the housing 2, as shown below. Figure 22 As shown, the developing cartridge 1 also includes a support member 2a disposed on the housing 2. The chip assembly 11 is supported by the support member 2a. Specifically, at least the movable member A94 is supported by the support member 2a, and the chip 7 can move together with the movable member A94. The conductor A92 has a first contact portion A921 for contacting the stylus in the device and a second contact portion A922 for contacting the chip electrical contact 72. In the following text, the chip electrical contact 72 is disposed on one surface of the substrate 71.

[0158] Figure 24A and Figure 24B The developing cartridge 1 is in a state where it is installed onto the drum unit or onto the device. At this time, the direction of movement of the movable component A94 is neither perpendicular nor parallel to the surface of the substrate 71 where the chip electrical contacts 72 are located, while the chip 7 can move together with the movable component A94. Preferably, the extension direction of the surface is parallel to the direction of movement of the movable component A94. Therefore, when the movable component A94 moves from... Figure 24A The position shown is towards Figure 24B During the movement of the position shown, the surface can be pressed against the second contact portion A922, thereby making the second contact portion A922 form a stable electrical contact with the chip electrical contact 72.

[0159] Example 12

[0160] like Figure 25 and Figure 26 As shown, similar to Embodiment Eleven, the chip assembly 11 in this embodiment is also disposed on the housing 2, but the position of the chip 7 in the movable part A94 in this embodiment is different from that in Embodiment Eleven, as shown below. Figure 26 The extension direction of the surface of the substrate 71 where the chip electrical contact 72 is provided is not parallel to the movement direction of the movable member A94. Instead, the surface is located below the second contact portion A922 in a third direction. In this way, when the chip 7 moves upward together with the movable member A94, the second contact portion A922 and the chip electrical contact 72 can form a stable electrical contact.

[0161] In summary, the power input section 26b in the conductive element 26 can be electrically connected to one of the first power output section 101 and the second power output section 102 to receive power, and then output to at least one of the developing element 31, the powder feeding element 32, and the developer adjusting element 29 through the power output section (at least one of the developing element power supply section 26c, the powder feeding element power supply section 26d, and the adjusting element power supply section 26e). Preferably, the conductive element 26 is not provided with a developing element power supply section 26c for direct electrical connection with the developing element shaft 311, that is, the developing element 31 is not in direct electrical contact with the conductive element 26. The developing element 31 is connected to the developing element shaft 311 via a power input section 26b located radially outward from the developing element shaft 311. The developing layer 312 on the side receives power from at least one of the powder feeding member 32 and the developer adjusting member 29. During the operation of the developing cartridge 1, even if the developing member 31 rotates continuously, there is no need to worry about friction between the developing member shaft 311 and the conductive member 26 causing the electrical connection between them to become unstable. At the same time, the positions where the developing member adjusting member 29 contacts the developing member 31 / developing layer 311 and the positions where the powder feeding member 32 contacts the developing member 31 / developing layer 311 are far away from the positions where the developing member 31 and the photosensitive drum are close to each other. In this way, even if uncontrollable vibration occurs between the developing member and the photosensitive drum, the developing member 31 can stably receive power.
