A fixing unit for an image forming device is provided to keep good insulation properties of a heat roller while maximizing heating efficiency, and reduce a warming up time from a standby mode in the initial driving. A fixing unit for an image forming device includes a heat roller(10), and a pressing roller facing the heat roller. The heat roller has a heat pipe(12), an induction coil(11) mounted to an inner surface of the heat pipe and entirely enamel-coated on its surface uniformly for insulation, and a first insulation layer for insulating the heat pipe with respect to the induction coil, wherein the induction coil is adhered to the first insulation layer by a thermoplastic adhesive.
