<p>An image heating apparatus (A) includes an endless belt (1) for heating an image (T) on a recording material (P); a plurality of supporting members (2,3) on which the belt (1) is trained; magnetic flux generating means (7), disposed outside of the belt (1), for generating heat in the belt (1) by a magnetic flux, the magnetic flux generating means (7) being effective to cause induction heating both in a region of the belt (1) between the supporting members (2,3) and in at least one of the regions of the belt (1) trained on the supporting members (2,3); a temperature detecting element (TH1;TH2) for detecting a temperature of the belt (1) in the region between the supporting members (2,3) at a position across the belt (1) from the magnetic flux generating means (7); and electric power supply shut-off means (100) for shutting off electric power supply to the magnetic flux generating means (7) on the basis of an output of the temperature detecting element (TH1,TH2).</p> |
