。[Claims for Utility Model Registration] A temperature control device for a heat roller having a heat roller and a temperature control means for controlling the heat roller to a predetermined temperature, comprising: a temperature sensor for detecting the surface temperature of the heat roller; The bimetal is configured such that the temperature sensor is brought into contact with the heat roller until the heat roller reaches the predetermined temperature, and when the heat roller reaches the predetermined temperature, the bimetal is bent in a direction to separate the temperature sensor from the heat roller. Temperature control of the heat roller, characterized in that when the temperature detector detects a temperature of the heat roller exceeding the predetermined temperature, power supply to the heat roller is cut off based on a signal from the detector. Device.
