PURPOSE:To enhance the durability and the reliability of a device by eliminating the problem of the scratch, the jiggling or the like of a film caused by a groove or a swollen part generated by trimming processing for correcting the total resistance value of a electricity conductive exothermic resistor as for the film heating system heating device using a thermal resistant and insulating base and a ceramic heater formed on the base and fundamentally constituted of the electricity conductive exothermic resistor as a heating body. CONSTITUTION:In the heating device imparting the heat of the heating body 2 to a material to be heated P through a heat insulating film 3 by making the film 3 press-contact with the heating body 2 by a pressure member 4 and travel and introducing the material P between the film 3 of a nip part N formed between the heating body 2 and the pressure member 4 by interposing the film 3 and the pressure member 4, places 22a and 22b where the power-supply exothermic resistor is corrected in order to correct the total resistance value are positioned distant from the nip part N. |
