置。[Claims for Utility Model Registration] 1. A heat fixing device comprising a heat roller, a heating means for heating the heat roller, an auxiliary roller that presses into contact with the heat roller, and a temperature detection means for detecting the surface temperature of the heat roller. In the apparatus, a non-contact sensor is used as the temperature detection means, the non-contact sensor is arranged near the heat roller, and a cover is provided to surround the non-contact sensor part to regulate the flow of heat to the heat-sensitive part of the non-contact sensor. Features of heat fixing device. 2. The heat fixing device according to claim 1, characterized in that the heat flow generated in the rotational direction of the heat roller is regulated by adjusting a gap between the heat roller and the cover. 3. The heat fixing device according to claim 1, wherein the cover is made of a heat-resistant heat insulating material. 4. The heat fixing device according to claim 1, wherein the heat-sensitive portion of the non-contact sensor and a member supporting the heat-sensitive portion are also enclosed by a cover. 5. The heat fixing device according to claim 1, characterized in that the heat roller is forcibly rotated at a temperature lower than the control temperature to shorten the heat-up time.
