ABSTRACT:
A heating apparatus includes a magnetic field generator that generates an alternating magnetic field, a rotatable member disposed in the alternating magnetic field and capable of generating heat by electromagnetic induction, a temperature detector that detects a temperature of the rotatable member, a comparator that compares the detected temperature to a target temperature: and a controller that controls electric energy supply to the magnetic field generator based on detected temperatures of different positions of the rotatable member.
