PURPOSE:To obtain a separation claw driving device of simple structure which has no mechanical coupling part and is easy in timing adjustment by providing an abutting part to a separation claw or a separation claw driving shaft to which the separation claw is fitted and providing an electromagnetic driving means which abuts on the abutting part. CONSTITUTION:When a switch SW is on, the separation claw 2 is pressed against an image carrier drum 1 because a movable piece 4 is moved down by an electromagnetic driving means (solenoid) 3 to lower the abutting member 6 fitted to a driving shaft 5 with the tension of a spring 7. A transfer sheet is separated from the drum 1 by the separation claw 2 as shown by a chain line S. When the switch SW is turned off, the movable piece 4 moves up to press up the abutting member 6, so the abutting claw 2 rotates as shown by an arrow (b) and is released from being pressed against the drum 1. The switch SW is turned on and off with a signal from a control part 8, so the timing is easily adjusted. |
