Abstract:
A fixing device includes an induction heater constructed of an exciting coil, a first pair of degaussing coils, and a second pair of degaussing coils. A controller turns off the exciting coil while the controller turns on one of the first pair of degaussing coils and the second pair of degaussing coils and at the same time turns off the other one of the first pair of degaussing coils and the second pair of degaussing coils, and then turns on the exciting coil for an extra time period corresponding to reserved power not supplied to the exciting coil while the exciting coil is turned off.
