Abstract

A torque receiving assembly, a photosensitive drum and a process cartridge having such torque receiving assembly. The torque receiving assembly having a body having an axis and having an accommodating chamber; a driven shaft disposed coaxially with the body, the driven shaft including a guide stem and a coupling head provided at one axial end of the guide stem, the guide stem having a pair of output arms which extend outwardly in a radial direction, the coupling head having a plurality of projections; wherein a pair of input arms are provided at an inner wall of the accommodating chamber and configured for abutting with the output arms; the guide stem is movable in the axial direction relative to the body, the torque receiving assembly further comprises a distance-limiting mechanism that defines a maximum distance the driven shaft is able to move relative to the body in the axis direction. The photosensitive drum and process cartridge according to the present invention both include the torque receiving assembly.
