Abstract
An image heating device includes a heater generating heat upon electric power supply, and a film whose one surface slidably contacts the heater, and whose other surface moves together with a recording material bearing an image while contacting the recording material. The image on the recording material is heated by heat from the heater through the film. The device also includes a thermoprotector having a bimetal which mechanically changes in order to disconnect electric power supply to the heater when there is an excessive temperature rise. The bimetal of the thermoprotector contacts the heater.
