Abstract: The image forming apparatus, includes a conveyor belt for bearing a recording material, capable of suppressing an image blur caused by a separating discharge at the separation of the recording material from the conveyor belt. To fix record materials on a transportation belt, the recording material is charged by a adhering member to electrically adhere the recording material to the conveyor belt. When the recording material is separated from the conveyor belt, a separating discharge occurs between the recording material and the conveyor belt, as the recording material is charged. In order to reduce the faulty of the toner image on the recording material caused by the separating discharge, the voltage applied to the adhering member is controlled for example according to a current which the recording material receives at the transfer position to mutually cancel the charge received at the transfer position by the adhering member.

Abstract: A toner image formed on an image bearing member is transferred onto a recording material so as to overflow from an edge portion of the recording material, thereby enabling the toner image to be formed so as to extend to the edge portion of the recording material. To suppress the deposition of the toner in the edge portion of the recording material, a cleaning member for cleaning the edge portion of the recording material obtained after the fixing is provided. In order to make a trailing edge of the recording material come into contact with the cleaning member, the recording material which has passed through a fixing apparatus is temporarily switched back, thereby allowing the trailing edge portion of the recording material to collide with the cleaning member.
