Fixing device and image forming apparatus

A fixing device comprising:

• an exciting coil to generate a magnetic flux;
• a heat generation layer disposed opposite the exciting coil to generate heat by the magnetic flux from the exciting coil;
• a temperature sensitive magnetic body disposed opposite the exciting coil via the heat generation layer, the temperature sensitive magnetic body to obtain and lose magnetism at a temperature defined by a Curie temperature by composition adjustment to selectively create a heating region and a non-heating region of the heat generation layer;
• and
• a degausser made of a non-magnetic material having an electrical resistivity smaller than an electrical resistivity of the temperature sensitive magnetic body, the degausser disposed opposite the exciting coil with an interval in a range of from about 4.2 mm to about 8.2 mm,
• wherein the heat generation layer and the temperature sensitive magnetic body are tubular,
• wherein the degausser includes an opposed face disposed opposite the exciting coil and contoured to correspond to an inner circumferential surface of the temperature sensitive magnetic body, and
• wherein the opposed face of the degausser is arcuate.
