Abstract
In a fixing apparatus of an embodiment of the invention, a heat roller forwardly and reversely rotated by a drive motor capable of forwardly and reversely rotating is heated by an induction heating coil also when it is reversely rotated. Further, the roller control temperature of the heat roller by a control system is adjusted according to a time of forward rotation of the heat roller and a time of reverse rotation, or a time when the heat roller and a press roller are separated from each other and a time when they are in contact with each other. Besides, after a specified time has passed since an instruction of reverse rotation or forward rotation by a drive signal, output of the induction heating coil is tuned on.
