Abstract
A belt failure detecting mechanism includes a rocking arm connected to a ground contact portion and an urging member configured to urge one end of the rocking arm against an inner surface of an end of a heating belt. When the end of the heating belt is not broken, the end of the rocking arm is in contact with the inner surface of the end of the heating belt, and the other end of the rocking arm does not contact to a detection switch so that an electric power is supplied to a heating device. When the end of the heating belt is broken, the end of the rocking arm is displaced to an outer side of the heating belt so that the other end of the rocking arm contacts to an electric element so that a fuse is blown to stop the electric power supplied to the heating device.
