Abstract
A copying machine for carrying out simplex, duplex and composite copying operations, wherein a sheet is re-fed to an image forming section in a duplex or composite copying mode. The machine includes two sheet discharge sections, a size evaluating device for judging the size of a sheet in the course of sheet transport, and a reversible roller pair disposed adjacent one of the discharge sections. When the sheet has a size fit for re-feeding for a second image formation in the duplex copying mode, the reversible roller pair is controlled to re-feed the sheet in a switchback fashion to the image forming section. When the sheet is too small, the reversible roller pair discharges the sheet through to the discharge section.
