Claims

[Scope of utility model registration request]

During the transfer process of a laser printer, the paper with the toner image transferred is passed through a heated roll to fix the paper, and in order to clean the dirt that adheres to the heated roll surface, the paper is pressed against the heated roll and moves slightly. In a fixing device that has a retractable strip member and has a detection bar and a detection switch at the final end of the strip member for detecting the completion of winding of the strip member, there is a contact between the detection bar and the detection switch that is in contact with the detection bar. The actuator is rotatably supported on the main body of the device and is normally biased to a non-operating position by a spring, and the other end of the actuator is provided with a contact portion that is in contact with the detection bar and is connected to the detection switch while the actuator rotates. A cleaning device for a fixing device comprising a cam portion that keeps the fuser in an operating state.
