ーラの温度制御装置。 A heating roller temperature control device configured to detect the temperature of a heating roller of a copying machine using a temperature sensor and control the temperature based on the feedback thereof.
After the heater is heated, the heater is turned off for a toff time, and the temperature of the temperature sensor when the heater is turned off and the temperature of the temperature sensor after the toff time are respectively detected, and based on this, the temperature of the heater after the toff time is calculated. The temperature of the heating roller is characterized in that a calculation unit is provided to calculate further heating time required for the heater based on the calculated temperature, and the heater is heated for the heating time output from the calculation unit. Control device.
