ABSTRACT:
A fixing device has a magnetic field generator; an electric power supplier for electric power supply to the magnetic field generator; electric power controller for controlling an electric power value to be supplied by the electric power supplier; a fixing member, disposed in the magnetic field, having an electroconductive layer which generates heat by eddy current generated by the magnetic field; a temperature detecting member for detecting a temperature of the fixing member; a discriminator for discriminating whether the apparatus is in order by comparing a detected temperature to a reference temperature in a period from a start of heating the fixing member to arrival at a predetermined temperature; and a reference temperature changer for changing the reference temperature on the basis of the supplied electric power value upon the electric power controller changing the electric power value.
