PROBLEM TO BE SOLVED: To provide an inexpensive heating fixing device capable of reducing the distance between a heating roller and a heating coil by a simple means, capable of enhancing heating efficiency without adding a magnetic core, and superior in workability when repairing and replacing the heating coil. SOLUTION: This electromagnetic induction system heating fixing device is formed by arranging the heating coil on the lengthwise directional inner peripheral side of the cylindrical heating roller, and is constituted so that the heating coil 1 is rotatably arranged in the heating fixing device so that a heat resistant insulated wire 1C is wound on the surface of a coil bobbin 1B for arranging electrodes 1A and 1a on both ends, and is adhered and fixed by a heat resistant adhesive, and the winding start side 1S and the winding finish side 1F are connected to the electrodes 1A and 1a, and electric power is supplied to the heating coil 1 via contact point electrodes 3A and 3a arranged on the heating fixing device casing side in response to the electrode 1A and 1a.
