An induction heating roller apparatus that varies temperature distribution in the axial direction of a heating roller. The apparatus includes a heating roller and a plurality of induction coils arranged separately along an axial direction of the heating roller. The heating roller includes a secondary coil that is air-core transfer coupled to the induction coils. The apparatus further includes a plurality of capacitors, each being connected to one of the induction coils to form a resonance circuit. At least one of the resonance circuits has a resonance point that differs from the remaining resonance circuits.
