Abstract
An image fixing apparatus includes a heater; an endless film movable together with a supporting member for supporting a toner image, in which the toner image is heated by heat from the heater through the film; a driver for driving the film; and a limiter for limiting the lateral position of the film. At least a part of the endless film is limited by the limiter and is substantially tension-free when the film is driven.
