Abstract:
A process cartridge comprises a photosensitive drum and a developing roller. A coupling member is provided adjacent to one axial end of the developing roller. The coupling member includes a driven portion, and an intermediary portion configured and positioned to engage with the driven portion. The intermediary portion is also configured to be movable relative to the driven portion in a direction crossing the axis of the developing roller while maintaining engagement with the driven portion. The coupling member further includes a driving portion configured and positioned to receive a driving force for rotating the developing roller. The driving portion is also configured to engage with the intermediary portion, and to be movable relative to the intermediary portion in a direction crossing the axis of the developing roller while maintaining engagement with the intermediary portion.

Claim (Index 1):
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, wherein the main assembly includes a rotatable first main assembly drive transmission member and a rotatable second main assembly drive transmission member, said process cartridge comprising:\n an electrophotographic photosensitive drum; a drum unit containing said electrophotographic photosensitive drum; a developing roller for developing an electrostatic latent image formed on said electrophotographic photosensitive drum with a developer; a developing unit containing said developing roller and movably connected with said drum unit, said developing unit being movable relative to said drum unit between a contact position in which said developing roller is contacted to said electrophotographic photosensitive drum and a spaced position in which said developing roller is spaced from said electrophotographic photosensitive drum; a drum coupling member, provided on one axial end of said electrophotographic photosensitive drum, for engaging with the first main assembly drive transmission member and transmitting a first rotational driving force to the electrophotographic photosensitive drum, when said process cartridge is mounted to the main assembly of the apparatus along an axial direction of said electrophotographic photosensitive drum; and a shaft coupling member, provided on one axial end of said developing roller, for transmitting a second rotational driving force with a deviation permitted between an axis of the second main assembly drive transmission member and an axis of said developing roller, wherein said shaft coupling member includes an engaging portion for engaging with the second main assembly drive transmission member and receiving the second rotational driving force, when said process cartridge is mounted to the main assembly of the apparatus; said engaging portion is movable in a direction crossing with the axial direction of said developing roller; and when said process cartridge enters said main assembly of the apparatus with said developing unit positioned in the spaced position, an axis of said engaging portion is deviated from the axis of said developing roller with respect to the crossing direction.
