Claims

1. A processing box, The photosensitive drum can rotate around its axis of rotation. The charging component can charge the photosensitive drum; The developing roller can deposit developer onto the photosensitive drum; The second unit includes the photosensitive drum; The first unit includes the developing roller, and the first unit is movable relative to the second unit between a developing position where the developing roller can deposit developer onto the photosensitive drum and a separation position where at least part of the developing roller is separated from the photosensitive drum; The separating force receiving section can receive a force when the first unit is located at the developing position, causing the first unit to move from the developing position to the separating position; The contact force receiving portion, when the first unit is located at the separation position, can receive a force that causes the first unit to move from the separation position to the developing position and project along the direction extending along the rotation axis of the photosensitive drum. The contact force receiving portion is closer to the rotation axis of the photosensitive drum than the separation force receiving portion. The feature is that, when the first unit is in the separated position, the photosensitive drum has a first side close to the charging member and a second side further away from the charging member than the first side. A second line tangent to the outer surface of the photosensitive drum is drawn on the second side of the photosensitive drum. When viewed along the direction extending along the rotation axis of the photosensitive drum, the second line divides the processing box into a first part and a second part. A first line passing through the rotation axis of the photosensitive drum and the rotation axis of the charging member is drawn, and the second line intersects the first line. The rotation axis of the photosensitive drum and the rotation axis of the charging member are located in the first part, and at least one of the contact force receiving part and the separation force receiving part is also located in the first part.

2. The process cartridge according to claim 1, wherein, Both the contact force receiving portion and the separation force receiving portion are located in the first portion.

3. The process cartridge of claim 1, wherein, The developing roller can rotate about its rotation axis. In a direction intersecting the length direction of the processing cartridge, the rotation axis of the charging component is closer to the rotation axis of the developing roller than the rotation axis of the photosensitive drum.

4. The process cartridge of claim 1, wherein, The charging component is a charging roller with an outer diameter of D, wherein 1mm ≤ D ≤ 7mm.

5. The process cartridge of claim 4 wherein, 2mm≦D≦5mm.

6. The process cartridge of claim 1, wherein, The first unit includes a first housing, the second unit includes a second housing, the first housing and the second housing are connected to each other, the second housing includes a first cover located at one end in the length direction of the second housing and a second cover located at the other end in the length direction of the second frame, and a main body portion located between the first cover and the second cover for containing waste developer, at least one of the first cover and the second cover being integrally formed with the main body portion.

7. The process cartridge of claim 6 wherein, The first cover, the second cover, and the main body are integrally formed.

8. The process cartridge of claim 1, wherein, The processing cartridge further includes a coupling portion and a chip. The coupling portion can receive an external driving force to drive the developing roller or the photosensitive drum to rotate. The chip has a chip electrical contact surface. In the length direction of the processing cartridge, the coupling portion and the chip electrical contact surface are located at the same end of the processing cartridge.
