Abstract
A process cartridge includes a photosensitive drum and a coupling member operatively connected to the photosensitive drum. The coupling member is movable between a position in which an axis of the coupling member is substantially coaxial with an axis of the photosensitive drum and a position in which the axis of the coupling member is not substantially coaxial with the axis of the photosensitive drum.
Claims12
A process cartridge comprising:
- a casing;
- developer contained within the casing;
- a photosensitive drum rotatably supported in the casing to permit rotation about an axis of the photosensitive drum;
- a developing roller rotatably supported in the casing to permit rotation about an axis of the developing roller, the developing roller being configured to develop a latent image formed on the photosensitive drum with the developer;
- and
- a coupling member having an axis about which the coupling member is rotatable and a free end portion for receiving a rotational force, the free end portion including at least one projection that is open to the axis of the coupling member, the coupling member being operatively connected to the photosensitive drum and the developing roller in order to transmit the rotational force to the photosensitive drum and the developing roller,
- wherein the coupling member is movable between a position in which the axis of the coupling member is substantially coaxial with the axis of the photosensitive drum and a position in which the axis of the coupling member is not substantially coaxial with the axis of the photosensitive drum.
