Abstract
PURPOSE: To detect the temperature of a fixing roller without damaging it by providing a resin sheet to contact with the object measured, together with an elastic member for pressing the sheet, the elastic member being provided with a cavity in which a heat-sensitive element is embedded to detect the surface temperature of the object being measured.
CONSTITUTION: A heat-resisting resin sheet 1 and an adiabatic elastic member 3 are held by means of a holding member 2, the elastic member 3 being provided with a cavity 8 in which a heat-sensitive element 4 is embedded. 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 resin sheet 1 to constantly contact closely with the object measured along its surface, the distance between the surface measured and the heat-sensitive element 4 is kept constant, so that thermal resistance has no variation, and a stable detection output can be obtained. Moreover, the elastic member 3, which has a little radiation, is not affected by the environmental temperature, and the resin sheet 1, which is soft, is not influencing damages on the object measured.
