Abstract
A fixing apparatus includes an induction coil for generating a magnetic field upon electric power supply thereto; a fixing rotatable member for induction heat generation by the magnetic field generated by the induction coil; temperature detector for detecting a temperature of the fixing rotatable member; determining unit for determining an electric power value to be supplied to the induction coil on the basis of a detected temperature by the temperature detector; and a controller for controlling the electric power supply to the induction coil on the basis of the electric power value determined by the determining unit. The controller substantially continues to supply the electric power while the electric power value determined by the determining unit is higher than a predetermined value, and effects an ON/OFF control of rendering on and off the electric power supply when the electric power value is lower than the predetermined value.
