Abstract
The present invention is a fixing device for use in an electrophotographic apparatus arranged in a structure in which a high-frequency current is flowed through an induction coil provided close to an endless member having a metal layer made of a conductive material and the endless member is caused to generate heat to heat a material to be fixed. This fixing device is characterized in that, when a start-up operation is started by electrically conducting the induction coil, the endless member is rotated after the metal layer reaches a temperature higher than a final setting temperature, and for a predetermined time from starting rotation of the endless member, a high-frequency current having a size corresponding to a control value of a temperature lower than the final setting temperature and higher than a target temperature is supplied to the coil.
