Abstract
An image heating apparatus includes a heater, an endless film contacting the heater and a back-up member cooperative with the heater to form a nip with the film sandwiched between it and the heater. A recording material having an image is passed between the back-up member and the film to heat the image by heat from the heater through the film. A guide is disposed for guiding the film and allowing the film to extend loosely around the guide. The film is under tension at least upstream of the nip and in the nip when the film is driven and is not guided by the guide between the upstream guide portion and the nip.
