Patent ID: 8682215

Claim:
A process cartridge comprising: a casing; a photosensitive drum having an axis L 1 , the photosensitive drum being rotatably supported in the casing to permit rotation about the axis L 1 ; and a coupling member having an axis L 2 , the coupling member including (i) a first end portion connected to the photosensitive drum, (ii) a second end portion, and (iii) a connecting portion connecting the first end portion and the second end portion, wherein the second end portion includes at least one pair of projections, with each of the projections including a facing portion that faces the axis L 2 , each facing portion being open to the axis L 2 , wherein a diameter of an imaginary circle that is tangent to the facing portions of the projections is greater than a maximum dimension of the connecting portion in a direction perpendicular to the axis L 2 , and wherein the coupling member is movable between a first position in which the axis L 2 of the coupling member is coaxial with the axis L 1 of the photosensitive drum, and a second position in which the axis L 2 of the coupling member is inclined with respect to the axis L 1 of the photosensitive drum.
