PURPOSE:To prevent the deterioration of the image quality with a simple constitution, by reversing and stopping an image forming matter so that the contact line between the image forming matter and a cleaning blade is set back to the position of a magnetic roller after the copying procedure is over. CONSTITUTION:A photosensitive drum 1 turns toward an arrow mark, and the residual toner on the drum 1 is scraped off by a blade 2a and cleaned. Then the drum 1 is reversed as soon as the copying procedure is over so that the contact line between the blade 2a and the drum 1 is set back to the position of a magnetic collector roller 2b. |
