  • Patent number: 5543907
    Abstract: A control circuit changes a sorting mode of a sorter corresponding to a state whether an original is both-sided or not, or whether or not a plurality of originals are simultaneously reproduced in one round of copying process when images of a plurality of originals are distributively reproduced on the same side of a transfer sheet, or whether a mode of the number of sheets of original and copy mode are for both sides mode or composite mode. With such a control, a sorting mode process is prohibited when a required transfer sheet is one irrespective of whether the number of sheets of original is one or not.
