Abstract: The image fixing apparatus forms a cleaning nip portion by pressing a web roll-up portion on a fixing rotation member with a feeding roller, a used portion for cleaning of the web is fed from a cleaning nip portion formation area, and during non-cleaning, a roller is at a waiting position at which the roller is farther from the fixing rotation member than its position during cleaning so as to separate the web roll-up portion from the fixing rotation member. Accordingly, it is possible to reduce degradation of a cleaning ability due to a toner component held by the used portion of the cleaning web.

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.
