An automatic duplex copying machine with a circulating document handler is characterized in that a plurality of single-sided-image bearing documents are piled on the circulating handler and a document page having been copied on a front side on a copy paper is sheltered in a copier-paper discharge path of the circulating document handler. Upon the occurrence of a paper jamming during copying another document page to be copied on the rear side of the copy paper, another document is sheltered into a document reverse tray of the circulating handler. The document with the front side page sheltered in the paper discharge path is forwarded into a document table, again, to conduct a supplemental copy. After that, the document with the front side page is sheltered in the document discharge path and the document with the rear side page is forwarded into the document table, again.
