  • FIXING APPARATUS FOR IMAGE FORMING APPARATUS
    Publication number: 20080118265
    Abstract: A fixing apparatus according to an embodiment of the present invention controls, using a CPU and a temperature comparator, an inverter circuit that supplies electric power to an induction heating coil and performs temperature control for a heat roller. The CPU adjusts and controls a power value supplied by the inverter circuit. When the adjustment and control of the power value by the CPU is late, the inverter circuit is ON-OFF controlled by the temperature comparator.

  • FIXING DEVICE FOR IMAGE FORMING APPARATUS
    Publication number: 20080118266
    Abstract: A fixing device according to an embodiment of the present invention heats a metal conductive layer of a heat roller using an induction current generating coil. In order to supplement a heat capacity of the heat roller, a press roller having a large heat capacity is heated by a halogen lamp. During a start of activation of an image forming apparatus, when a printer control circuit is started, the supply of electric power to the halogen lamp is started before warming-up is started.
