Abstract

PURPOSE:To facilitate replacement and other servicing of the photosensitive drum, by providing a blocking member to block or not to block the displacement when the photosensitive drum and driving member are relatively displaced, and a switching member which cooperates therewith. CONSTITUTION:A photosensitive drum 5 is fitted to a shaft 20 by means of a cam plate 26 which is engaged with a pin 25, and is rotated by the shaft 20. A ring 51 is fitted through sleeves 19, 52 provided at the other end thereof and a winding spring clutch 53 which permits rotation only in one direction. Usually, when the drum 5 is rotated by the cam plate 26, the sleeve 52 also turns together, so that the ring 51 turns together, thereby not moving the spring clutch 25. When the rotary shaft 20 stops, the spring clutch 53 is actuated to stop the drum 5 immediately. When the upper lid 17 of the device main body is opened in the direction of arrow for replacing or servicing the drum, since a tooth 51a catches on the spring 28, the sleeve 51 is rotated in the counterclockwise direction, so that the drum 5 may rotate freely with respect to the rotary shaft 20.
