Abstract
An image forming apparatus comprises a cartridge that includes a developing roller and a coupling member for receiving a rotational force for rotating the developing roller. A cylindrical member movably supports one end portion of the coupling member inside of the cylindrical member. A cylindrical member side force receiving portion is provided inside the cylindrical member. A first regulating portion, provided inside of the cylindrical member, prevents one end portion of the coupling member from disengaging in an axial direction of the cylindrical member. A second regulating portion regulates deformations of the first regulating portion outward of the cylindrical member in the radial direction in a state in which one end portion of the coupling member is mounted to the inside of the cylindrical member. The apparatus also includes a driving motor and a driving shaft engageable with the coupling member of the cartridge.
