Abstract

PURPOSE:To improve thermal efficiency and to reduce warm-up time by rotating only the metallic cylinder which has internally a rolled shaped heater and has high heat conductivity. CONSTITUTION:A roll type heat fixing device 1 is constituted of a metallic cylinder 2, a heater 3, a motor 9, etc. The cylinder 2 is a metallic cylinder having high heat conductivity. The heater 3 is disposed in proximity as far as possible to the inside of the cylinder 2 and is wound with a ribbon heater into a double-layered roll shape. The ribbon heater is wound via an insulating sheet 6 around an electrically insulating and heat insulating layer (urethane, silicone sponge layer) 5 formed around a shaft 4. An insulating sheet 7 is fixed as wound on the surface of the heater 3. The cylinder 2 is supported via bearings 8 to the shaft 4 and is rotated by the motor 9, etc. The surface of the cylinder 2 is coated with ''Teflon''.
