Abstract
A method of removing a film which undesirably forms on a photoconductive element or similar image carrier of an image forming apparatus such as an electrophotographic copier, printer or facsimile machine. The method is implemented by a cleaning device having a cleaning sleeve which removed toner particles remaining on the image carrier after image transfer. In a film removing mode which is executed when an image forming mode for forming a toner image on the image carrier is not under way, the cleaning sleeve is rotated at a lower speed than in an ordinary cleaning mode so as to feed a greater amount of cleaning agent to a cleaning region. The rotation speed of image carrier and that of the cleaning sleeve are controlled in such a manner as to feed a predetermined adequate amount of cleaning agent for the removal of a film to the cleaning region at all times.
