Patent ID: 8280278

Claim:
A process cartridge comprising: a casing; a rotary member having an axis L 1 and having a flange at one end of the rotary member that is coaxial with axis L 1 , the rotary member 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 having (i) a rotational force transmitting portion engageable with the flange, (ii) a rotational force receiving portion, and (iii) a connecting portion that connects the rotational force receiving portion to the rotational force transmitting portion, 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 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, and wherein the maximum angle of inclination of the coupling member is limited by contact between the coupling member and the flange.
