A heating apparatus includes a magnetic flux generation means 25 and a rotatable induction heating element 21 for generating heat through electromagnetic induction by the action of magnetic flux generated by the magnetic flux generation means, and heats a material to be heated by causing the material to be heated to contact the induction heating element 21 . The heating apparatus further includes a thermistor detection means 28 for detecting a surface temperature of the induction heating element 21 , power supply circuits 101 - 104 for controlling power to be supplied to the magnetic flux generation means 25 on the basis of signals from the temperature detection, a Curie temperature reaching detection means 29 for detecting that the temperature of the induction heating element reaches the Curie temperature, and control circuits 100 and 104 for detecting that the material to be heated is wound around the induction heating element 21 on the basis of signals from the temperature detection means 28 and the Curie temperature reaching detection means 29.
