PURPOSE:To take automatically a multiple copy and a both-surface copy by providing a transfer material inverting mechanism which stores a transfer material in an intermediate tray by a switching means after an image is formed on the transfer material, and also inverts the transfer material by the switching means without image formation and then restores it in the intermediate tray. CONSTITUTION:When a both-surface copy is taken, the transfer material after fixation is stored in the intermediate tray 33 through a changeover guide 30 with an image-formed surface up, and then inverted and refed to a photosensive drum 19 to from an image on the reverse surface newly. When a multiple copy is taken, the transfer material stored in the intermediate tray 33 with a 1st- image-formed up is given the inversion period of the transfer material and image formation is not performed during the period; and the transfer material is refed to the intermediate tray 33 and restored in the intermediate tray 33 through the changeover guide 30 with the image-formed surface up. Then, the transfer material is fed out of the intermediate tray 33 again and the 2nd image is formed to complete the multiple copying operation. |
