PURPOSE:To reduce the size of a device and to perform both-surface recording speedily by providing a inverting and conveying device which receives copying paper to which a toner image is transferred by a transfer part from an image carrier and inverts and sends out it to another transfer device. CONSTITUTION:The toner image on the image carrier 1 is transferred to the copying paper P by a transfer device 10 and the copying paper P is separated from the surface 1 of the carrier by the inverting and conveying device 11 and rotated as shown by an arrow (a). When the toner-image transfer surface of the copying paper P conveyed by the device 11 finishes moving beyond the irradiation position of a flash exposure lamp 18, the device 11 is switched immediately to arrow-(b) rotation and the copying paper P is sent out to a pressure transfer roller 14. Consequently, the gap between a toner image transferred to the reverse surface of the copying paper P by the transfer device 10 and the toner image transferred to the reverse surface of the copying paper P by the roller 14 is shortened on the surface of the carrier 1, thereby shortening a both-surface copying operation time. |
