A photocopier having a duplex copy unit unable to stack a plurality of recording media thereon, wherein an image scanner is controlled such that the scanner reads the first document, then reads the first document and the second document alternately, and finally reads the second document. A medium feed device and the duplex copy unit are controlled such that one recording medium is fed from the medium feed device, then recording media are alternately fed from the medium feed device and duplex copy unit one at a time, and finally one recording media is fed from the duplex copy unit, thereby reducing the period of time necessary for reproducing the images of a document or documents on both sides of recording media and enhancing the productivity of the copier.
