(54) Heat apparatus for use in an image forming apparatus


(57) A fusing/fixing apparatus has an upper roller 1 that is rotatable, a lower roller 2 that follows the rotation of the upper roller 1, and a heating means for heating at least one of the first and second rollers 1 and 2. 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.
