Abstract:
A fixing device includes a rotatable fixing member, a pressing member, a motor, and an oil applier. The pressing member contacts the fixing member. The oil applier includes an application roller and an oil supply mechanism. The application roller applies oil to one of the fixing member and the pressing member. The oil supply mechanism supplies oil to the application roller. The motor is provided independent of other drivers, and supplies a driving force to the application roller to rotate the application roller at an arbitrary speed.
