Abstract
In a device for sensing a temperature of a fixing roller, a thermistor is provided on a flat upper surface of a support member made of a foamed silicone material, with a heat conductive material provided between them. A heatproof protective sheet is wrapped around so that the thermistor is partially sunk into the support member by the tightness of the wrapping. The heat conductive material is thereby deformed to the thermistor's shape. At the same time, the top part of the thermistor is always protruded from the upper part of the support member. A holder keeps this construction in contact with the circumferential surface of the fixing roller.
