Abstract

PURPOSE:To prevent an oil run and toner run-over by detecting a rotating speed at the time of an open rotation of a heat roll by an encoder, driving a pump by an encoder signal from the encoder, when the rotating speed becomes lower than a prescribed rotating speed, and supplying oil to felt. CONSTITUTION:A rotating speed at the time of an open rotation of a heat roll 3 is detected by an encoder 1a, and when the rotating speed becomes lower than a prescribed rotating speed, pumps 9-11 are driven by an encoder signal from the encoder 1a, and oil is supplied to felt 7. Accordingly, when the rotating speed becomes lower than the prescribed rotating speed, oil comes to be supplied, and the oil supply quantity at the time of an open rotation of the heat roll 3 becomes optimum. In such a way, an oil run and toner run-over can be prevented.
