Abstract

PURPOSE: To detect the temperature of a fixing roller without damaging it by providing a protective layer for the object to be measured, an elastic member for pressing the layer, a heat-sensitive element for detecting the surface temperature of the object to be measured between the layer and the elastic member, and a metal layer between the heat-sensitive device and the protective layer.
CONSTITUTION: A protective layer 1 of a heat-resisting resin sheet, and an adiabatic elastic member 3 are held by means of a holding member 2. A metal layer 9 of metal foil is provided betweeh the protective layer 1 and a heat-sensitive element 4. A pair of fixing rollers is formed of a fixing roller 6 as an object measured and a roller 11. The periphery of the heat-sensitive element 4, which is all made of resin, has a small heat capacity, so that a high sensitivity can be obtained. Since the elastic member 3 permits the protective layer 1 to constantly contact closely with the object measured along its surface, and the heat-sensitive element 4 is contacted with the protective layer 1 through the metal layer 9, the pressure on the protective layer 1 is weakened and dispersed, so that friction is difficult to occur. Thus, the damage to the object measured and the heat-sensitive element 4 due to the wear of the protective layer 1 can be prevented.
