Abstract: In an image forming apparatus, a cleaning blade, disposed on a downstream side of a transfer roller in a rotation direction of an image carrier, removes toner remaining on the image carrier after transfer of a toner image to an intermediate transfer member. After completion of an image forming operation, a controller causes the transfer roller to separate from the intermediate transfer member, cause the developing device to form on the image carrier a toner band to be supplied to the cleaning blade, and cause rotation of the image carrier to stop such that at least a part of the toner band formed on the image carrier stops within a section from a first position facing the transfer roller to a second position facing the cleaning blade in the rotation direction.

Abstract: An image forming apparatus includes a photosensitive member and a charging roller to which a direct current voltage is applied. A difference between a first potential (before charging) and a second potential (after charging) of a surface of the photosensitive member in an image forming operation is smaller than 100 V. The charging roller includes a shaft portion, an elastic layer provided on an outer periphery of the shaft portion, and a surface layer provided on an outer periphery of the elastic layer. A ten point height of roughness profile Rz (?m) and a root mean square slope R?q with respected to a surface of the charging roller satisfy Rz?7 and R?q?0.1.
