Abstract:
1. An image forming device comprising: a print portion configured to form an as yet unfixed developer image on a sheet; a first roller configured to be provided in a direction in which the sheet from the print portion is transported; a heating element configured to be provided in either the first roller or an endless belt wound around the first roller and generate heat by magnetic flux; a second roller configured to form a nip together with the heating element; a coil configured to have a coil hole facing the nip with a gap therebetween and operable of generating the magnetic flux; an induction heating circuit configured to supply the coil with a drive signal; an electrically insulating mold configured to have a through hole facing the coil hole and operable of supporting the coil, the mold causing the coil to face a coil surface to the nip; a mechanism configured to transport the sheet through the through hole of the mold and the coil hole of the coil to the nip; and a controller configured to cause the mechanism to transport the sheet to the nip and the induction heating circuit to perform the induction-heating.
