摘要： A paper separation claw is separated from a surface of a pressure roller by a drive source being turned ON at a time t2 before commencement of rotation of the pressure roller, and the paper separation claw is made to contact the surface of the pressure roller by the drive source being turned OFF after commencement of rotation (a time t4) of the pressure roller. Furthermore, the paper separation claw is separated from the surface of the pressure roller by the drive source being turned ON again before stopping of rotation (a time t5) of the pressure roller after an image forming operation of a single job is finished, and the paper separation claw is made to contact the surface of the pressure roller by the drive source being turned OFF again after stopping of rotation (a time t8) of the pressure roller.
