PURPOSE:To reduce the frequency of switching to reverse-surface copying operation to only one and to facilitate control over the both-surface copying operation by carrying out top-surface copying operation for all originals corresponding to add pages and then copying originals corresponding to even pages to reverse surfaces. CONSTITUTION:A both-surface copy conveyance path 34 is formed between an intermediate tray 22 and a switch-back conveyance path 33, and an inverted form conveyance path 35 is constituted between the intermediate tray 22 and the PS roller 21 in a copying machine body 2. An intermediate tray guide 23 and a form feeding belt 24 for the intermediate tray part are arranged at the intermediate tray 22. Consequently, originals are circulated twice by an original circulatory feeder to perform the top-surface copying operation in the 1st circulation for all originals corresponding to odd pages and also stack copying forms in the intermediate tray 22; and the originals are fed from the intermediate tray 22 in the 2nd circulation to form images of one-surface originals on both surfaces of the copying forms. |
