An image heating apparatus includes a coil; a rotatable image heating member for generating heat by a magnetic flux generated by the coil to heat an image on a recording material; a voltage source for applying a high frequency current to the coil; a temperature detecting member for detecting a temperature of the image heating member; control device for controlling electric power supply to the coil from the voltage source on the basis of an output of the temperature detecting member such that the temperature of the image heating member is maintained at a set temperature T; and protecting device for stopping the electric power supply to the coil when the output of the temperature detecting member indicates a predetermined abnormal temperature Te, wherein at least a part of the image heating member is made of a magnetism-adjusted alloy having a predetermined magnetic permeability decrease start temperature Tc′and a predetermined Curie temperature, and wherein T≰Tc′<Te<Tc.
