Abstract

An image forming apparatus comprises a main assembly of the image forming apparatus, with the main assembly including a driving shaft. The image forming apparatus also includes a cartridge detachably mountable to the main assembly of the image forming apparatus, the cartridge including (i) a photosensitive drum and (ii) a coupling positioned adjacent to an end portion of the photosensitive drum, with the coupling being movable in an axial direction of the photosensitive drum. The coupling is engageable with the driving shaft by the coupling moving in the axial direction in a state in which the cartridge is tilted relative to the main assembly of the image forming apparatus.

Claims (30)

1. An image forming apparatus comprising:

a main assembly of the image forming apparatus, the main assembly including a driving shaft; and

a cartridge detachably mountable to the main assembly of the image forming apparatus, the cartridge including (i) a photosensitive drum and (ii) a coupling positioned adjacent to an end portion of the photosensitive drum, with the coupling being movable in an axial direction of the photosensitive drum,

wherein the coupling is engageable with the driving shaft by the coupling moving in the axial direction in a state in which the cartridge is tilted relative to the main assembly of the image forming apparatus,

wherein the cartridge is provided with a first side where the coupling is positioned and a second side opposite to the first side, and

wherein, in a mounting direction that the cartridge is mounted to the main assembly of the image forming apparatus, the coupling is engageable with the driving shaft by the coupling moving in the axial direction so that the first side of the cartridge is downstream of the second side in the state in which the cartridge is tilted relative to the main apparatus of the image forming apparatus.

2. An image forming apparatus according to claim 1 , wherein the coupling is provided with a projection,

wherein the driving shaft is provided with a recess, and

wherein the coupling is engageable with the driving shaft by the projection of the coupling entering into the recess of the driving shaft.

3. An image forming apparatus according to claim 1 , wherein the driving shaft is constructed to be tiltable.

4. An image forming apparatus according to claim 1 , wherein the cartridge is provided with a movable portion contactable to the main assembly of the image forming apparatus, and

wherein an inclination of the cartridge relative to the main assembly of the image forming apparatus is changed by moving of the movable portion.

5. An image forming apparatus according to claim 4 , wherein the cartridge is provided with a first side where the coupling is located and a second side opposite to the first side, and

wherein the movable portion is located at the second side of the cartridge.

6. An image forming apparatus according to claim 4 , wherein the cartridge is provided with a first side where the coupling is located and a second side opposite to the first side, and

wherein the movable portion is located at the first side of the cartridge.

7. An image forming apparatus comprising:

a main assembly of the image forming apparatus, the main assembly including a driving shaft; and

a cartridge detachably mountable to the main assembly of the image forming apparatus, the cartridge including (i) a photosensitive drum and (ii) a coupling positioned adjacent to an end portion of the photosensitive drum, with the coupling being movable in an axial direction of the photosensitive drum,

wherein the coupling is engageable with the driving shaft by the coupling moving in the axial direction in a state in which the cartridge is tilted relative to the main assembly of the image forming apparatus,

wherein the cartridge is provided with a movable portion contactable to the main assembly of the image forming apparatus, and

wherein an inclination of the cartridge relative to the main assembly of the image forming apparatus is changed by moving of the movable portion.

8. An image forming apparatus according to claim 7 , wherein the coupling is provided with a projection,

wherein the driving shaft is provided with a recess, and

wherein the coupling is engageable with the driving shaft by the projection of the coupling entering into the recess of the driving shaft.

9. An image forming apparatus according to claim 7 , wherein the driving shaft is constructed to be tiltable.

10. An image forming apparatus according to claim 7 , wherein the cartridge is provided with a first side where the coupling is located and a second side opposite to the first side, and

wherein the movable portion is located at the second side of the cartridge.

11. An image forming apparatus according to claim 7 , wherein the cartridge is provided with a first side where the coupling is located and a second side opposite to the first side, and

wherein the movable portion is located at the first side of the cartridge.
