PURPOSE:To surely transmit torque by transmitting via a friction member pressed at one end face of a photoreceptor drum. CONSTITUTION:When one end section of a photoreceptor drum 11 is coupled with a coupling section 21 via the support member 2 of the photoreceptor drum 11 and a friction member 22 is relatively pressed to one end face of the photoreceptor drum 11 via a press section 23, the photoreceptor drum 11 is supported and torque can be transmitted. The slip between a pressing member and the friction member 22 can be restricted by a hook projection 25 formed on the face of the press section 23 in contact with the friction member 22 in particular. Torque can be transmitted more surely. |
