Fixing apparatus having a curie point heater and image forming apparatus
A fixing apparatus has a heater that includes a magnetic shunt alloy whose Curie temperature is set higher than a fixing temperature; an induction heater that generates an alternating magnetic field applied to the magnetic shunt alloy and performs electromagnetic-induction heating on the heater; and a body controller that controls the induction heater so as to adjust the fixing temperature in each fixing job. The body controller controls the induction heater so as to perform electromagnetic-induction heating on the heater, during a period between fixing jobs. The body controller thereby reduces a temperature difference generated on the heater between portions corresponding to paper feeding and non-paper feeding areas in a previously executed fixing job.
