Summary:PROBLEM TO BE SOLVED: To resolve the problem that a film of a coil wire (litz wire) may be melted and cause dielectric breakdown because the temperature of a coil rises by heat generation of the coil itself and radiant heat from a heat roll, or the like in an image fixing device provided with a fixing device in the induction heating system wherein the coil is arranged in the cylindrical heat roll made of a metallic conductor. SOLUTION: In the image fixing device provided with the fixing device of the induction heating system where the coil to heat the cylindrical heat roll made of a metallic conductor by induction heating is arranged inside the heat roll, a heat conductive member is provided which conducts heat of the coil out of the heat roll, and heat conducted out of the heat roll and the coil is radiated by this heat conductive member.
