Abstract
A fixing device for thermally fixing a toner image formed on a recording medium by an image forming apparatus is disclosed. A heat roller included in the fixing device is prevented from moving in its axial direction or thrust direction without causing any leak to occur. While a heating layer and a temperature sensor are electrically isolated from each other, the temperature sensor can accurately sense the surface temperature of the heat roller without damaging the surface of the heat roller.
