ABSTRACT:
A heat fixing device for a image reproduction machine includes a heat roller having a heat source for heat fixing a toner image on a copy paper, a temperature sensing element for sensing the temperature of the heat roller, and a temperature control element responsive to the output of the temperature sensing element for controlling the power supply to the heat source. The temperature sensing element and the temperature control element are integrally combined.
