Abstract
A fixing device capable of improving printing speed without increasingly the size of rollers, and making the surface temperature of the heating roller quickly reach a target temperature. The heating roller, which comes into contact with recording sheet having unfixed toner adhering to it, includes an elastic body of low heat conductivity and high heat resistance, and has metal foil formed tightly to the external circumferential surface thereof. This meal foil with a small heat capacity, by direct contact on its surface with the heating source, helps the surface of the heating roller quickly rise in temperature.
