Abstract

PURPOSE:To decrease the loads of toner at the time of driving a photosensitive drum and to prevent blocking by driving the photosensitive drum after a developing roller is driven and a toner chain on a sleeve starts self rotation. CONSTITUTION:The developing roller 23 is constituted by installing the sleeve 27 which can rotate on the outer periphery of a fixed magnet 26 and the sleeve 27 is driven by an AC motor 28 to be rotated counterclockwise, which is shown by an arrow. Now, the photosensitive drum 11 is made to start the rotation later than the sleeve 27 by a specified time tM. When the photosensitive drum 11 starts the rotation, the toner on the sleeve 27 has started the self rotation, so that the attractive force to the sleeve 27 becomes small. Thus, the loads of the toner when the photosensitive drum 11 starts the rotation becomes small and the blocking can be prevented.
