PURPOSE: To make a good copy, by placing a set of originals for copying on the feed tray of an original feeder, feeding the originals one by one to an exposure platen to expose an electrostatis drum imagewise, sending the first copies to another feed tray, and then repeating copying by use of these first copies as originals.

CONSTITUTION: Originals for copying are placed on a feed tray 1 of an original feeder 4, these originals are a successively sent to an exposure platen 5 with a separating roller 2, a feed roller 3, and a conveyor belt 6, and stopped with a stopping plate 7. After copying, the plate 7 is pulled in with a solenoid 9, and the originals are sent to a receiving tray 11. A toner image on a drum is transferred 17 to a transfer paper 18, fixed 22, and the first copies are placed on another original feed tray 29 through conveying members 25W28.
