In a fixing device according to this invention, coils are formed on a coil bobbin having a predetermined shape at an induction heating portion including a plurality of coils. In order to minimize the temperature difference of a heating roller in the axial direction, the coil bobbin has a shape for holding the interval between the coils at a predetermined interval.
