PROBLEM TO BE SOLVED: To provide a heating device which can reduce the load of a switching means connected to an electric conductor at the time of switching the closed circuit or the open circuit of the electric conductor by the switching means, and can reduce the generation of noise, and to provide a image forming device equipped with this heating device. SOLUTION: Opening timing when a switching circuit 31 switches a demagnetization coil 7 from the closed circuit to the open circuit, and conducting timing when the switching circuit 31 switches the demagnetization coil 7 from the open circuit to the closed circuit are set for only when induced electromotive force generated in the demagnetization coil 7 by the magnetic flux of an exciting coil 4 is a prescribed electric power value or lower.
