Abstract
A process cartridge comprises a photosensitive drum, a developing roller, and a coupling member. The coupling member is capable of inclining relative to the photosensitive drum such that the coupling axis inclines relative to the drum axis. A regulating portion surrounds the coupling member so as to confine the range of inclination of the coupling member. The regulating portion is provided with a recess that recesses in a direction away from the drum axis and away from the developing roller. An angle between the coupling axis and the drum axis is larger when at least a part of the coupling member is in the recess than when the coupling member contacts another portion of the regulating portion.

28. A process cartridge comprising:
-
i) a photosensitive drum rotatable about a drum axis thereof; ii) a rotatable developing roller configured to develop a latent image formed on said photosensitive drum; iii) a coupling member provided at an axial end portion of said photosensitive drum and rotatable about a coupling axis thereof so as to transmit a driving force to said photosensitive drum, said coupling member being capable of inclining relative to said photosensitive drum so that the coupling axis inclines relative to the drum axis; and iv) a regulating portion surrounding said coupling member to confine a range of the inclination of said coupling member, wherein said regulating portion is provided with a recess that recesses in a direction away from said drum axis and away from said developing roller, and wherein an angle between the coupling axis and the drum axis is larger when at least a part of said coupling member is in said recess than when said coupling member contacts another portion of said regulating portion. - View Dependent Claims (29, 30, 31, 32, 33)
