ABSTRACT:
A prior art temperature sensing element by supporting plates against a fixing roller would detect a temperature lower than an actual surface temperature of the fixing roller, because said heat-conductive supporting plates would be cooled by air flowing along said supporting plate, depriving a part of its heat of the temperature sensing element through the supporting plate.
According to present invention, a heat-insulating elastic body is disposed over said two supporting plates at one end threof, said temperature sensing element is placed as being projecting from the surface of the heat-insulating elastic body at the center thereof, the temperature sensing element and supporting plates are fastened (sticked) with the heat-resisting film larger in length and wide than the heat-insulating elastic body and each having an adhesive surface one side thereof, and the other end of each supporting plate is secured to a holder.
