ABSTRACT:
A copying apparatus provided with an automatic document feeder having a function for sequentially feeding a pair of documents and serially placing them onto a platen in the document feeding direction. In the copying apparatus, the operation of feeding a second document onto the platen is inhibited and the image forming operation to the image of a first document, is allows, when the first document is a size where the longer side thereof in parallel to the longer side of the platen, or the size of the first document is larger than the half of the platen. Meanwhile, one of a plurality of sheet feeders storing a relevant size of copy sheet is selected based on the size of a larger document fed onto the platen. Further, the optimum magnification is determined based on the size of a larger document fed onto the platen and the size of a copy sheet fed from the sheet feeder.
