Abstract:
1. A fixing apparatus comprising: an endless belt configured to fix an unfixed toner image on a sheet at a nip portion by heat; a first supporting roller and a second supporting roller configured to rotatably support an inner surface of the endless belt; a rotary member configured to form the nip portion in cooperation with the endless belt; a displacing mechanism configured to displace the first supporting roller so the endless belt is within a predetermined zone in a width direction of the endless belt; and a rubbing roller configured to rub an outer surface of the endless belt at a rubbing position where the rubbing roller causes the endless belt to be brought into press contact with the second supporting roller, wherein the rubbing position is a position that avoids a region where the endless belt is separated from the second supporting roller with a displacement of the first supporting roller.
