When an image forming medium 5 with a toner image 6 formed thereon is passed and pressed between the upper and lower rollers 1 and 2, the toner image 6 is fused and fixed on the image forming medium 5. The heating means is constructed by combining a halogen heater 3 and a sheathed heater 4. <IMAGE>
