PURPOSE:To contrive to improve the thermal efficiency of non-contact heating by providing a reflecting means for reflecting a far infrared radiation radiated from a far infrared radiation substance toward the surface of a recording material, in the periphery of a halogen lamp heater having the far infrared radiation substance on the surface of a glass tube. CONSTITUTION:A halogen lamp heater 1 has an electrode 7 on both ends of a sealed quartz glass tube 5, and in its inside, a tungsten filament 6 for connecting both the electrodes is provided, and on the surface of the quartz glass tube 5, a far infrared radiation substance layer 8 is provided. Also, in the periphery of the halogen lamp heater 1, a reflecting plate 2 for reflecting a far infrared radiation radiated from the far infrared radiation substance layer 8 toward the surface of a recording material 3 is placed. Accordingly, the radiated far infrared radiation reaches effectively the recording material 3 by the reflecting plate 2 and a toner 4 is fixed. In such a way, the thermal efficiency can be improved.
