Abstract
A fixing device includes a magnetic flux generating section having a coil which generates a magnetic flux when applying current, a fixing roller having a heat generating layer having a thickness of 100 μm or less formed along an outer peripheral surface of the fixing roller for generating heat through electromagnetic induction by the magnetic flux, a capacitor connected in series to the coil to constitute a series resonant circuit, and high frequency power supply circuits for applying voltage having a certain drive frequency to the series resonant circuit so as to make the fixing roller generate heat through the magnetic flux generating section. An image is fixed onto a sheet, which is transported in a state of being in pressure-contact with the outer peripheral surface of the fixing roller, by heat from the heat generating layer of the fixing roller.
