PURPOSE:To speed up printing time per sheet and to miniaturize an entire device even in the case of using an OHP sheet on the like taking much time for fixing as a transfer material. CONSTITUTION:The rotational force of a driving motor 17 makes a photo-sensitive drum 1 rotate through a gear 18, a double gear 19 (19a and 19b), and a gear 22, and simultaneously makes a transfer drum 5 rotate through the gear 18, the double gear 19 (19a and 19b), a gear 20, and a gear 21. Even when the drum 5 is separated from the drum 1 by an eccentric cam 30, the drum 5 is always rotated because the gear 20 is pressed to the gear 21 by a torsion coil spring 25. |
