Covering member and cartridge
A cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes an image bearing member; a frame; process means contactable to and actable on the image bearing member; a covering member detachably mounted to the frame to protect a surface of the image bearing member; and a spacing portion provided on the covering member and inserted between the image bearing member and the process means to space the image bearing member and the process means from each other, the spacing portion being movable relative to the covering member while being interposed between the image bearing member and the process means when the covering member is removed from the frame.
1. A cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, said cartridge comprising:
an image bearing member;
a frame;
process means contactable to and actable on said image bearing member;
a covering member mounted to said frame to protect a surface of said image bearing member and dismountable from said frame by moving in a direction crossing with an axis of said image bearing member; and
a spacing portion provided on said covering member and inserted between said image bearing member and said process means to space said image bearing member and said process means from each other, said spacing portion being movable relative to said covering member while being interposed between said image bearing member and said process means when said covering member is removed from said frame.
2. A cartridge according to claim 1 , wherein said spacing portion is rotatably engaged with said covering member.
3. A cartridge according to claim 1 , wherein said spacing portion is mounted to said covering member by a hinge portion.
4. A cartridge according to claim 1 , wherein said spacing portion is provided at each of one and the other axial ends of said image bearing member, which is a photosensitive drum.
5. A cartridge according to claim 1 , wherein said spacing portion is detachably mounted to said covering member.
6. A cartridge according to claim 1 , wherein said process means includes charging means for electrically charging said image bearing member.
7. A cartridge according to claim 6 , wherein said charging means includes a rubber portion, and a shaft supporting said rubber portion rotatably relative to said frame, and
wherein said spacing portion is inserted between the surface of said image bearing member and said shaft to space said image bearing member and said charging means from each other.
8. A cartridge according to claim 7 , further comprising a pressing member for urging said charging means to said image bearing member.
9. A cartridge according to claim 1 , wherein said process means includes developing means for developing an electrostatic latent image formed on said image bearing member.
10. A cartridge according to claim 9 , wherein said developing means includes a rubber portion, and a shaft supporting said rubber portion rotatably relative to said frame, and
wherein said spacing portion is inserted between the surface of said image bearing member and said shaft to space said image bearing member and said developing from each other.
11. A cartridge according to claim 10 , further comprising a pressing member for urging said developing means to said image bearing member.
12. A cartridge according to claim 1 , wherein said covering member includes a portion-to-be-locked for locking with said frame.
13. A cartridge according to claim 12 , wherein said covering member is provided between a first portion-to-be-locked and a second portion-to-be-locked provided at one and the other axial ends of said image bearing member, which is a photosensitive drum, respectively.
14. A covering member for use with a cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the electrophotographic image forming apparatus including an image bearing member, a frame, process means contactable to and actable on the image bearing member, said covering member being, mounted to said frame to protect a surface of said image bearing member and being dismountable from said frame by moving in a direction crossing with an axis of said image bearing member, said covering member comprising:
a spacing portion provided on said covering member and inserted between said image bearing member and said process means to space said image bearing member and said process means from each other, said spacing portion being movable relative to said covering member while being interposed between said image bearing member and said process means when said covering member is removed from said frame.
15. A covering member according to claim 14 , wherein said spacing portion is rotatably engaged with said covering member.
16. A covering member according to claim 14 , wherein said spacing portion is mounted to said covering member by a hinge portion.
17. A covering member according to claim 14 , wherein said spacing portion is provided at each of one and the other axial ends of said image bearing member which is a photosensitive drum.
18. A covering member according to claim 14 , wherein said spacing portion is detachably mounted to said covering member.
19. A covering member according to claim 14 , wherein said covering member includes a portion-to-be-locked for locking with said frame.
20. A covering member according to claim 14 , wherein said covering member is provided between a first portion-to-be-locked and a second portion-to-be-locked provided at one and the other axial ends of said image bearing member, which is a photosensitive drum, respectively.
