Abstract

PURPOSE: To perform temperature controlling of the heater with the simple device by disposing a temperature measuring sensor to the moving surface of the object in the position opposing to the heating source on the side opposite from the heating source in such a manner as to receive heat directly from the heating source in the heater for heat treatment such as heat fixing device of a facsimile apparatus.
CONSTITUTION: In a device that the recording paper 7 having undergone development is conveyed on a guide 3 and is heat-fixed, a temperature measuring sensor 4 is provided on the opposite side of a heater 1 with the guide 3 in-between, and a temperature control circuit which controls the output of the heater 1 is connected thereto. A hole 8 is provided to the guide 3 and the heater and the sensor 4 are thermally coupled. When preheating is started, the output of the heater 1 is so controlled by the sensor 4 and temperature control circuit that the preheating temperature becomes of the specified value. Next, when the conveyed recording paper 7 shields the hole 8, the temperature of the sensor 4 lowers and the output of the heater 1 assumes an increased heating state. After the passage of the recording paper 7, the temperature of the sensor 4 rises again, and therefore the preheating state is automatically resumed.
