Abstract
A heating apparatus has a magnetic flux generator and a rotatable induction heating element for generating heat through electromagnetic induction by the action of magnetic flux generated by the magnetic flux generator, and heats a material to be heated by causing the material to be heated to contact the induction heating element. The heating apparatus further includes a thermistor for detecting a surface temperature of the induction heating element, power supply circuits for controlling power to be supplied to the magnetic flux generator on the basis of signals from the temperature detection, a Curie temperature reaching detector for detecting that the temperature of the induction heating element reaches the Curie temperature, and control circuits for detecting that the material to be heated is wound around the induction heating element on the basis of signals from the thermistor and the Curie temperature reaching detector.
