Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of an image forming apparatus according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of a set of four process cartridges of different colors according to an embodiment of the present application. The image forming apparatus includes an image forming apparatus main body 200 and a process cartridge 100, and the process cartridge 100 is detachably mounted in the image forming apparatus main body 200.
Specifically, the image forming apparatus further includes a cartridge mount 201, a first pushing portion 202, and a second pushing portion 203. The cartridge mount 201 is slidably attached to the image forming apparatus main body 200, and mounts the process cartridge 100. The first pushing portion 202 and the second pushing portion 203 are respectively provided on one side of the image forming apparatus main body 200.

Referring to fig. 3, fig. 3 is a sectional view of a process cartridge according to an embodiment of the present application. The process cartridge 100 includes a powder cartridge 1, a waste cartridge 2, and an elastic separating member 3. The powder cylinder 1 and the waste cylinder 2 are movably connected, the powder cylinder 1 comprises a developing roller 12, and the waste cylinder 2 comprises a photosensitive drum 22. The elastic separation assembly 3 is used for generating displacement when receiving the driving force exerted by the second pushing part 203, and then the elastic separation assembly 3 pushes the powder cylinder 1 and/or the waste cylinder 2 to move or rotate, so that the developing roller 12 is separated from the photosensitive drum 22.
Specifically, when the second pushing portion 203 applies a driving force in the first direction to the elastic separating assembly 3, the elastic separating assembly 3 is displaced to drive the powder cylinder 1 and the waste cylinder 2 to move away from each other, so that the developing roller 12 is separated from the photosensitive drum 22; when the second pushing portion 203 releases the driving force applied to the elastic separating member 3, the elastic separating member 3 returns to the initial position (the position where the elastic separating member 3 is located without being subjected to a force) to bring the developing roller 12 into contact with the photosensitive drum 22, wherein the first direction is the direction opposite to the mounting direction of the process cartridge 100.
As shown in fig. 3, the process cartridge 100 further includes an elastic member. The powder cartridge 1 includes a powder cartridge body 11 and a developing roller 12, the powder cartridge body 11 having a first containing chamber 111, the first containing chamber 111 being for containing printing powder.

When the second pushing portion 203 applies a driving force to the driver 31 in the first direction, the driver 31 moves in the first direction and pushes the separating member 33 to move in the second direction, so that the separating member 33 is inserted between the developing roller 12 and the photosensitive drum 22 and the developing roller 12 is separated from the photosensitive drum 22. When the second pushing portion 203 releases the driving force applied to the driving member 31, the driving member 31 moves toward the connecting member 13 by the elastic force of the first elastic member 32, that is, the driving member 31 moves away from the separating member 33, so that the driving member 31 is separated from the separating member 33. At this time, the separating member 33 is moved in a direction away from the developing roller 12 and the photosensitive drum 22 by the second elastic member, and the developing roller 12 and the photosensitive drum 22 are brought into contact with each other by the elastic member.

In this embodiment, an end of the driving member 31 away from the first elastic member 32 has a first inclined surface 311, an end of the separating member 33 close to the driving member 31 has a second inclined surface 331, and the first inclined surface 311 and the second inclined surface 331 are correspondingly disposed, so as to change the moving direction. It will be appreciated that in other embodiments, the change in direction of movement may be achieved by a rack and pinion or bevel gear.
In order to prevent the separating member 33 from damaging the developing roller 12 and the photosensitive drum 22 when the separating member 33 is inserted between the developing roller 12 and the photosensitive drum 22, one end of the separating member 33, which is inserted between the developing roller 12 and the photosensitive drum 22, is made of a flexible material, and the end is provided with a pointed structure, thereby making the process of separating the developing roller 12 from the photosensitive drum 22 smoother.

The first position-limiting portion 313 is connected to the connecting member 13 via the first elastic member 32, and the first position-limiting portion 313 and the first position-limiting member 14 can be matched for position limitation. The second position-limiting portion 314 can cooperate with the second position-limiting member 15 for limiting, and the first inclined surface 311 is disposed on the second position-limiting portion 314.
Referring to fig. 4, fig. 4 is a sectional view of a process cartridge according to another embodiment of the present application.

The elastic separating component 3 is connected to the end cover 4, and when the elastic separating component 3 receives a driving force along the first direction, the elastic separating component 3 moves towards the second direction to push the powder cylinder 1 to rotate, so that the developing roller 12 is separated from the photosensitive drum 22. Wherein the first direction is a direction opposite to the mounting direction of the process cartridge 100, and the second direction is a direction perpendicular to the first direction.
Specifically, the end cap 4 includes a cover body 41 and a connecting part 42, the cover body 41 has a mounting cavity 411, the mounting cavity 411 is opened with an opening 412, and the connecting part 42 is connected to the inner wall of the mounting cavity 411.
