Abstract
Disclosed is a fixing apparatus, in which a cylindrical roller comprising a thin metal layer having a small heat capacity is heated by an induction heating and, when the toner image transferred onto a paper sheet is fixed to the paper sheet, it is possible to control accurately the temperature on the surface of the cylindrical roller. Where the toner image formation on the paper sheet having a width smaller than the length of the cylindrical roller and the fixing operation of the toner image are carried out repeatedly, it is possible to prevent the temperature elevation in the edge portion of the roller. In addition, the power consumption can be saved.
