Patent ID: 8116661

Claim:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus that includes a driving member, said process cartridge comprising: (A) a photosensitive drum; (B) a developing roller configured and positioned to (a) develop an electrostatic latent image formed on said photosensitive drum and (b) be rotatable about an axis thereof; (C) a coupling member provided adjacent to one axial end of said developing roller, said coupling member including: (i) a driven portion provided adjacent to the one axial end of said developing roller; (ii) an intermediary portion configured and positioned to (a) engage with said driven portion and (b) be movable relative to said driven portion in a direction crossing the axis of said developing roller while maintaining engagement with said driven portion; and (iii) a driving portion configured and positioned to (a) receive a driving force for rotating said developing roller, (b) engage with said intermediary portion and (c) be movable relative to said intermediary portion in a direction which crosses the axis of said developing roller and which is different from the direction of the movement of said intermediary portion while maintaining engagement with said intermediary portion; and (D) a retaining portion configured and positioned to retain an axis of said driving portion in a position which is deviated from the axis of said developing roller in a direction crossing the axis of said developing roller so as to enable engagement of said driving portion with the driving member when said process cartridge is inserted into the main assembly of the apparatus with said developing roller being in contact with said photosensitive drum.
