Abstract
PURPOSE: To obtain always constant fixing characteristic irrespective of ambient temperatures by controlling a fixing roller according to the temperature suited for the temperature of a support which supports the toner powder image to be fixed, according to said temperature.
CONSTITUTION: A detector 16 for detecting the heating temperature of the peripheral surface of an upper fixing roller 2 is provided. This detector 16 has a supporting member 18 which is supported rotatably about a shaft 17 and is composed of, e.g., copper or stainless steel, of superior heat conductivity, and a thermistor 19 is mounted to the lower part thereof. This member is being held lightly pressure-contacted to the peripheral surface of the fixing roller 2. The upper part of the supporting member 18 consists of an end portion 18a of a large area and a neck portion 18b of a narrow width; these both portions 18a, 18b protruding to outside the fixing device 1 through the opening 14a formed in the upper part of a heat-insulating casing 14. As a result of this, the fixing roller is controlled to the temperature suited for the temperature of the supporting body according to this and therefore always constant fixing characteristic may be obtained.
