Abstract
A printer includes, in its fixing device operable to fix toner particles onto a recording medium, a heating roller containing magnetic metal, a fixing roller disposed parallel to the heating roller, an endless belt containing magnetic metal bridged across the heating roller and the fixing roller. The printer also includes a press roller pressed to the fixing roller via the endless belt and the recording medium, and a coil core being operable to produce magnetic fields so as to cause both of the heating roller and the endless belt to generate heat with the magnetic metals contained therein.
