PROBLEM TO BE SOLVED: To provide a fixing device and an image forming apparatus which greatly decrease toner soil on the leading edge of a transfer material even in the use of a soft type roller as a fixing roller. SOLUTION: The fixing device has: a fixing roller 30 in which the surface of an arbor 50 is covered with an elastic layer 51 and the elastic layer 51 is covered with a film of fluorocarbon resin 52, and a separation claw 60 which slidingly contacts the fixing roller. In the fixing device, the heat conductivity of the elastic layer 51 is 0.9 W/m.°C or higher or the thickness of the elastic layer is 500μor less. Thus, satisfactory heat conductivity is ensured.
