Abstract:
    To improve the fixing ability in the fixing device, and simultaneously prevent hot offset occurring during continuous fixing process. In the interior of a cored bar of a heat roll is mounted a heater lamp, and heat roll is maintained at a first set temperature enabling heat fix. The heat roll is controlled and maintained at the first set temperature at the initial fixing process, and when performing a continuous fixing process, it is switched and controlled to a second set temperature T2 lower than the first set temperature but enabling fixing. Thereby, the fixing ability could be maintained well, preventing hot offset.
