Abstract

PURPOSE:To eliminate the waste of energy by providing a main fixing heater for heating a small size paper passing area and a bus-fixing heater for heating a passing area of only large size paper, varying the lighting duty of the sub- fixing heater in accordance with a temperature at the time of passing of small size paper, and transferring surplus power to the main fixing heater. CONSTITUTION:At the time of passing of small size paper 3, the lighting duty of a sub-fixing heater 6 is varied in accordance with a paper size, thickness of paper, humidity of paper, temperature of paper and machine temperature, respectively, so that surplus power is transferred to a main fixing heater 5. That is, in case of passing of large size paper 2, the main and sub-fixing heaters 5, 6 are controlled simultaneously by a temperature detecting element 30, and on the other hand, in case of passing of small size paper 3, the main fixing heater 5 is controlled by the temperature detecting element 30, but the sub-fixing heater 6 is controlled by the lighting duty which is set in accordance with a temperature of a fixing roller 1, thickness of paper, humidity of paper, temperature of paper, and machine temperature. In such a way, it does not occur that energy is consumed uselessly.
