Abstract

A fixing device includes a heating element fixedly supported during a fixing procedure, a film, apparatus enabling the film to slide against the heating element, and a pressurizing roller for pressing a recording material on which a toner image is supported against the film. The heating element has a substrate, a heat generating layer provided on the substrate, and a heat-melting portion provided on the substrate. The heat-melting portion melts at a temperature higher than the fixing temperature and lower than the withstanding temperature of the substrate and thereby disconnects the heat generating layer from its power source.
