A heating roller for fixation has a hollow body with a wall thickness of 1-3 mm. A deposit prevention layer is formed on the outer surface of the roller body. The roller body has excellent heat conductivity. A resistance heat generating member is bonded on and anchored to the inner surface of the roller body. The resistance heat generating member is a flexible heat generating sheet which is formed by adhering a resistance heat generating body composed of predetermined patterns of resistance members, formed of stainless steel or copper foil, on the surface of an insulating film material, made of a polyimide resin, that has heat resistance and insulating characteristics.
