<p>An electrophotographic apparatus includes an image forming mechanism (10) for forming an image on a paper sheet, and a magnetic cleaning system (14) for magnetically cleaning a surface of an image carrier (1) of the mechanism for each cycle of image formation. A mechanical cleaning system (20) is provided for mechanically cleaning the image carrier. The mechanical cleaning system includes a blade (22) movable between a contact position where it contacts with the surface of the carrier and an off position where it is kept apart from the surface. The blade is intermittently moved to the contact position, by a drive mechanism (25, 25a) and a control unit (30), for predetermined operating times at predetermined time intervals. The blade is arranged to be manually operable through a lever (24) attached to the blade.</p> |
