Abstract
A cartridge includes: a rotatable member, including a metal shaft, supported movably in an axial direction of the metal shaft; an electroconductive member, supported movably in the axial direction in contact to an end surface of the metal shaft in one end side of the metal shaft, for constituting an electroconductive path for electrically connecting the metal shaft and a contact member provided in an image forming apparatus main assembly; an urging portion for urging the metal shaft via the electroconductive member in a direction from the one end side to another end side of the metal shaft; and an abutting portion for positioning the rotatable member by being abutted by the metal shaft. The electroconductive member includes a contact portion to the end surface of the metal shaft, at a portion other than a rotation center portion of the metal shaft at the end surface.
