Since the process cartridge is detachably mounted with respect to the apparatus main body, maintenance of the apparatus is facilitated. An electrophotographic image forming apparatus employing an electrophotographic image forming manner is operated as follows: an electrophotographic photosensitive member uniformly charged by a charger is subjected to selective exposure by light of an image forming apparatus to form an electrostatic latent image, which is developed with toner by a developer into a toner image, and the formed toner image is transferred onto a recording medium by a transfer to form an image on a recording material.
Generally, a photosensitive assembly of the process cartridge is provided with a power receiving device which is engaged with a machine driving device in the image forming apparatus to drive the photosensitive assembly to perform a rotational movement to drive the entire process cartridge to operate. However, the photosensitive assembly is required to be detachably mounted in the image forming apparatus with the process cartridge, and therefore, when the process cartridge is required to be taken out of the image forming apparatus, the power receiving device is disengaged from the machine driving device to ensure that the process cartridge is smoothly taken out of the image forming apparatus; when the processing box is installed in the imaging equipment to carry out printing operation, the power receiving device is required to be meshed with the machine driving device, so that the photosensitive assembly is ensured to successfully receive driving force.

The second transfer member 28 may also be integrally formed with the flange member 26 to further simplify the construction of the power transfer assembly 20. The regulated member 23 is connected to the power receiving portion 21 and the first transmitting member 22 through the shaft pin 24. The shaft pin 24 sequentially passes through the first hole 23a of the regulated member 23, the second hole 22a of the first transmitting member 22, and the third hole 21a of the power receiving portion 21, thus fixing the regulated member 23, the first transmitting member 22, and the power receiving portion 21. Preferably, the shaft pin 24 connects the regulated member 23, the first transmission member 22 and the power transmission portion 21 to fix the power transmission assembly 20, and alternatively, the regulated member 23 and the first transmission member 22 may be formed as an integral structure, the power receiving portion 21 and the first transmission member 22 may be formed as an integral structure, or the regulated member 23, the first transmission member 22 and the power receiving portion may be formed as an integral structure. The first elastic member 25 is provided between the regulated member 23 and the flange member 26, and has one end abutting against the regulated member 23 and the other end abutting against the flange member 26.

The adjustment assembly 30 is used to control the telescoping of the power receiving portion and to limit the rotational dwell position of the power receiving portion, as will be described in detail hereinafter. In this embodiment, the power transmission assembly 20 and the regulating assembly 30 together constitute a driving assembly of the process cartridge. Alternatively, the adjusting member 33 may be connected to the driving side and the opposite driving side of the frame 1 from another place of the frame, and the flange member 26 is preferably directly sleeved coaxially with the photosensitive drum 3, alternatively, the photosensitive drum 3 may be driven to rotate by a gear linkage structure. It should be noted that, since the mounting between the components is required to have a tolerance, the power receiving portion 21 may have a slight runout when expanding and contracting in the axial direction thereof, and therefore, the expansion and contraction of the power receiving portion in the axial direction thereof described in the present embodiment may be understood as the expansion and contraction of the power receiving portion 21 substantially in the direction of the own rotation axis thereof.
As shown in fig. 3 and 7, the adjustment assembly 30 includes a lever 31, a second elastic member 32, and an adjustment part 33. A bracket 2 is mounted on the side of the frame 1, and one end of the second elastic member 32 abuts against the bracket 2 and the other end abuts against the control lever 31. The frame 1 is further provided with lever guide sliding parts 1a and 1b for guiding the movement track of the lever 31, and the guide sliding parts 1a and 1b are configured in a T-shaped groove structure not only for guiding the movement of the lever 31 but also for preventing the release of the lever 31 from the frame 1.

The control lever 31 is provided with a diagonal slide groove 31c, and the diagonal slide groove 31c in this embodiment is specifically configured as an elongated hole having a length direction at an acute angle to the axial direction of the regulating member 33, and a force-receiving pin 33a on the regulating member 33 is inserted into the diagonal slide groove 31c, and the axial direction of the regulating member 33 is the same as the axial direction of the photosensitive drum 3. When the control lever 31 slides along the slide guides 1a and 1b, the force pin 33a slides along the inclined slide groove 31c and drives the regulating member 33 to move in the axial direction. The arrangement of the slide guiding parts 1a and 1b and the protrusions 1c enables the control rod 31 to move along a preset track, two inclined sliding grooves 31c are arranged, two inclined sliding grooves 31c are oppositely arranged on two sides of the protrusions 1c, and the stress pin 33a is arranged in the two inclined sliding grooves 31c, so that the adjustment part 33 is guaranteed not to rotate in the axial expansion process driven by the control rod 31, namely, the adjustment part 33 does not rotate relative to the frame 1 in the moving process. Alternatively, the adjusting member 33 may be restricted by the frame 1 to prevent the adjusting member 33 from rotating, so long as a structure for preventing the adjusting member 33 from rotating is provided on the frame 1, for example, a recess is provided on the frame 1, and a protrusion matching the recess is provided on the adjusting member 33 to prevent the adjusting member 33 from rotating.
As shown in fig. 7 to 9, the bracket 2 is provided with a first abutting portion 2a, the main body 31b of the lever 31 is provided with a second abutting portion 31d, one end of the second elastic member 32 abuts against the first abutting portion 2a, the other end abuts against the second abutting portion 31d, the lever 31 is movable by receiving an external force, and when the process cartridge is in a free state, the elastic force of the second elastic member 32 presses the lever 31 to move the lever 31 in a direction away from the regulating member 33, and the force receiving pin 33a moves along the inclined chute 31c to drive the regulating member 33 to move from the inside to the outside of the frame 1, that is, the regulating member 33 moves in a direction away from the power transmission unit 20. When the control lever 31 receives an external force F, the control lever 31 moves in a direction approaching the adjusting member 33 against the elastic force of the second elastic member 32, and the force receiving pin 33a moves along the inclined chute 31c to drive the adjusting member 33 to move from the outer side to the inner side of the frame 1, i.e., the adjusting member 33 moves in a direction approaching the power transmission assembly 20.
As shown in fig. 5, 10, 11, and 12, the regulated member 23 is provided with a pair of force receiving portions 23b, the pair of force receiving portions 23b are disposed opposite to each other in the circumferential direction of the regulated member 23, and a pair of grooves 23c are provided between the pair of force receiving portions 23 b. The force receiving surface of the force receiving portion 23b in contact with the adjustment lever 33b is constructed in an arch shape with both ends thereof being higher in the middle, specifically, as shown in fig. 12, a cross section is made through the rotation axis of the member to be adjusted 23 and the pair of grooves 23c, and the force receiving surface is seen in the cross section direction as an arch shape with both ends thereof being lower in the middle. Alternatively, the stress surface may be provided in other shapes, such as a taper, as long as the stress surface satisfies that the height of both ends is lower than the middle. The adjustment lever 33b controls the rotation of the member to be adjusted 23 by abutting against the force receiving portion 23 b. The end of the regulated member 23 where the groove 23c is located is referred to as the root of the regulated member 23, the end opposite to the groove 23c is referred to as the mouth of the regulated member 23, when the regulating lever 33b is moved from a position near the mouth of the regulated member 23 to the root position of the regulated member 23, since the regulating lever 33b is inserted into the regulating part 33 while the regulating part 33 is again restrained by the control lever 31 so as not to be selectable, the regulating lever 33b drives the regulated member 23 to rotate by contact with the force receiving part 23b and finally enters the pair of grooves 23c, the groove 23c is set to match the peripheral dimension of the regulating lever 33b, i.e., when the regulating lever 33b enters the pair of grooves 23c, the regulating lever 33b can position the groove 23c so that the regulated member 23 does not rotate or rotates only slightly. In the rotational direction of the power transmission assembly 20, the position of the adjusting part 33 is fixed with respect to the frame 1, the position of the adjusting lever 33b inserted into the adjusting part 33 is also fixed, the position of the regulated member 23 is also fixed when the adjusting lever 33b enters the pair of grooves 23c, and the power receiving portion 21 and the regulated member 23 are also connected by the shaft pin 24, so that the position of the power receiving portion 21 is also fixed. The pair of grooves 23c are provided for better positioning of the regulated member 23, and the grooves 23c may not be provided additionally, and a recess may be formed at a position where the pair of force receiving portions 23b of the regulated member 23 are connected to each other, and the effect of the grooves 23c may be achieved by the cooperation of the regulating lever 33b with the recess. Alternatively, the structure of the adjusting lever 33a on the adjusting part 33 and the structure of the force receiving part 23b on the adjusted member 23 may be replaced, a rod-like structure similar to the adjusting lever is provided on the adjusted member 23, an arch-like protrusion structure similar to the structure of the force receiving part is provided on the adjusting part 33, and the rotation stop position of the adjusted member may be controlled by the movement of the adjusting part.
As shown in fig. 13 and 14, the process cartridge is mounted into the image forming apparatus in the mounting direction X. A stopper 151 is provided in the image forming apparatus at a position close to the driving head 150, which may cause a situation in which the process cartridge is mounted as in fig. 13, that is, the power receiving claw portion 21b of the power receiving portion 21 interferes with the bottom end column 150a of the driving head 150, thereby causing the process cartridge to be unable to complete the mounting.
As shown in fig. 15 to 19, in order to overcome the situation shown in fig. 13 occurring during the mounting of the process cartridge, the resting position of the regulated member 23 in the rotation direction is controlled by the regulating means 33 in the present embodiment to finally control the resting position of the power receiving portion 21 in the rotation direction. In the present embodiment, the direction of the line connecting the pair of power receiving claw portions 21b is referred to as the P direction, and the extending direction of the opening between the pair of power receiving claw portions 21b is referred to as the Q direction. It is preferable that the connecting line direction P of the pair of power receiving claw portions 21b is perpendicular to the mounting direction X of the process cartridge, that is, the extending direction Q of the opening between the pair of power receiving claw portions 21b is parallel to the mounting direction X of the process cartridge, so that the opening between the pair of claw portions 21b on the power receiving portion 21 faces the bottom end column 150a of the driving head 150 in the image forming apparatus, and the process cartridge is mounted smoothly. Since the opening distance between the pair of power receiving claw portions 21b of the power receiving portion 21 is larger than that of the driving head 150 in the image forming apparatus so far, the opening extending direction Q between the pair of power receiving claw portions 21b can also be installed at an angle to the installation direction X, as long as the installation of the process cartridge is completed without the pair of claw portions 21b interfering with the driving head 150 as in fig. 13. As shown in fig. 11 and 12, when the process cartridge is mounted, the machine door of the image forming apparatus is closed, which applies a force F to the lever 31, the lever 31 controls the regulating member 33 to move in a direction approaching the power transmission assembly 20, and the regulating lever 33b provided on the regulating member 33 is moved out of the groove 23c on the regulated member 23 and above the pair of force receiving portions 23b, in which position the regulating lever 33b allows the regulated member 23 to rotate without interfering with the regulating lever 33 b. The elastic force of the first elastic member 25 urges the regulated member 23 so that the regulated member 23 moves from the inside to the outside of the frame 1, the power receiving portion 21 moves together with the regulated member 23 and engages with the driving head 150 in the image forming apparatus, while when the power receiving portion 21 protrudes to the outside of the frame 1, the first transmitting member 22 engages with the second transmitting member 28, and the driving head 150 in the image forming apparatus drives the respective rotating members in the process cartridge to rotate to complete the image forming action.
When the process cartridge is to be replaced, the machine door of the image forming apparatus is opened, the pressing of the control member 33 is canceled by the machine door, the control lever 31 is moved away from the square of the regulating member 33 by the elastic force of the second elastic member 32, the regulating member 33 is moved away from the power transmission assembly 20 by the driving of the control lever 31, the regulating lever 33b provided on the regulating member 33 controls the retraction of the regulated member 23, the first transmitting member 22 is disengaged from the second transmitting member 28 while the regulated member 23 is retracted, the regulated member 23 is freely rotatable, the groove 23c on the regulated member 23 is engaged with the regulating lever 33b and is positioned by the regulating lever 33b at a fixed position of the regulated member 23 in the rotation direction, the power receiving portion 21 is also fixed at a fixed position in the rotation direction, that is, the position where the pair of power receiving claw portions 21b of the power receiving portion 21 do not interfere with the bottom end cylinder 150a of the driving head 150, and the process cartridge is smoothly taken out. Since the regulating member 33 is freely movable in the axial direction with respect to the regulated member 23 in this embodiment, even if the regulated member 23 cannot be retracted due to the power receiving portion 21 being blocked by the upper inclined surface 151a of the stopper 151 in the image forming apparatus and thus cannot be retracted, the regulating member 33 can control the rotation of the regulated member 23, thereby ensuring that the power receiving portion 21 does not interfere with the driving head 150 in the image forming apparatus when the process cartridge is taken out.
