Abstract
Certain embodiments provide an image forming device including: a print portion; a first roller provided in a sheet transportation direction; a heating element provided in either the first roller or an endless belt wound around the first roller and generates heat by magnetic flux; a second roller that forms a nip together with the heating element; a coil that has a coil hole facing the nip with a gap therebetween and generates the magnetic flux; an induction heating circuit that supplies the coil with a drive signal; an insulating mold that has a through hole facing the coil hole and supports the coil; a mechanism that transports the sheet through the through hole to the nip; and a controller that causes the mechanism to transport the sheet to the nip and the induction heating circuit to perform the induction-heating.
