Abstract
An automatic duplex electrophotographic copying machine comprises a copying machine main body including a toner image transfer portion, a sorter having switch-back device to reverse the travel direction of a copy paper and wherein the sorter is to be mounted on the copying machine main body near a paper outlet, and a desk for mounting the copying machine main body and including a transport device communicating from the sorter to the paper feeding section of the copying machine main body. The copying machine main body, the sorter and the desk are detachable from one another. In the duplex copying mode, a single-side copied paper discharged from the paper outlet of the copying machine main body is turned over by the switch-back device in the sorter and transported by the transport device in the desk back to the toner image transfer portion.
