<p><P>PROBLEM TO BE SOLVED: To prevent a paper which has not been separated from a photoreceptor from being jammed in a cleaning part, then, to prevent the breakage of a cleaning apparatus and the photoreceptor, and also, to prevent an operator from being forced to perform a difficult jamming processing work. <P>SOLUTION: When the front end of the paper reaches a position where a peeling pawl 13 should come in contact after the leading end of the peeling pawl 13 is retreated from the surface of the photoreceptor drum 3 due to the delay of a paper carrying timing, the paper never come in contact with a part on a transfer belt 6E with which a potential detecting roller 6D comes in contact, consequently, the detection signal of a voltage detection circuit 65 never rises. When this state is detected, driving data output to a motor driver 74 is stopped by a CPU 71, and the rotational drive of the photoreceptor drum by a motor M1 is stopped. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
