In an image forming apparatus of this invention, a cleaning bias of opposite polarity to toner is applied to a conductive cleaning blade, thus enhancing the cleaning performance of the cleaning blade. Thus, even for substantially spherical toner, good cleaning is provided without increasing the pressing force of the cleaning blade to a photoconductive drum. The durability of the photoconductive member and the cleaning blade is improved and maintenance is reduced.
