To provide a heating device having a prescribed Curie point, heating a material to be heated material P by the heat of a heating member 1 generating heat by the action of magnetic flux generated from a magnetic flux generating means 3, prevented from the occurrence of hindrance caused by variations of Curie point of the heating member 1 at manufacturing, or run-off from allowed common difference of temperature caused by the deterioration of durability.
The heating device has a judging member judging whether the Curie point of the heating member 1 mounted on the heating device is within a prescribed range or not, and a control means stopping the heat generation of the heating member when it is determined by the determining member so that the Curie point is out of the prescribed range.
