Patent ID: 8630564

Claim:
A process cartridge comprising: a rotary member having an axis L 1 , the rotary member being rotatable about the axis L 1 ; and a coupling member having an axis L 2 , the coupling member having (i) a first end portion connected to the rotary member, (ii) a second end portion, and (iii) a connecting portion connecting the first end portion and the second end portion, wherein the coupling member is movable between a first portion in which the axis L 2 of the coupling member is coaxial with the axis L 1 of the rotary member, 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 rotary member, wherein the second end portion comprises a pair of projections, each projection including a tip, and wherein, if a first plane is defined as a plane in which the tips of the projections moved when the coupling member moves between the first position and the second position, and a second plane is defined as a plane that is perpendicular to the first plane and contains the axis L 1 , then the projections are positioned on opposite sides of the second plane when the coupling member is in the first position, and the projections are positioned on the same side of the second plane when the coupling member is in the second position.
