Abstract
A fixing unit includes a heating rotor, a pressure rotor, an induction coil, and a magnetic core portion having a bypass core portion and a magnetic flux shielding member. The induction coil generates a magnetic flux to heat the heating rotor. A Curie point of the bypass core portion is higher than the temperature of the bypass core portion when the temperature of the heating rotor has reached a fixing temperature for fixing of the transfer material, and lower than the temperature of the bypass core portion when the temperature of the heating rotor has reached a heat-resistant temperature. The magnetic flux shielding member is configured about the periphery of the bypass core portion in close proximity or abutment with the bypass core portion.
