Abstract
PURPOSE: To prevent the occurrence of friction flaws and filming of toners and achieve the longer life of a photosensitive drum by evenly depositing toners on the drum by recovered toners prior to cleaning with a blade.
CONSTITUTION: The nonprinting part 15 on a photosensitive drum 1 is charged to opposite polarity by being subjected to corona charging by a charge-erasing charger 9 so as to become the polarity opposite from the polarity of uniform charging corona and further a magnet roll 13 is approached to the photosensitive drum 1 so that the toners are deposited on the nonprinting part 15 as well by the ears of the removed toners. Hence, the occurrence of friction flaws and filming of toners in the nonprinting part 15 is obviated by the lubricating action of the toners and the longer life of the photoreceptor may be achieved.
