ABSTRACT:
In an image forming apparatus having two-face copy mode, an image reader can read a document image placed on a platen along a subscan scan direction and along a direction reverse to the subscan direction. The image reader includes an image sensor for reading a document image along a main scan direction and along a direction reverse to the main scan direction. In the normal image mode and in the reverse image mode, a normal image and a reverse image of a document are formed by controlling the reading direction and the subscan direction. When a stapler is used to staple a plurality of copy papers, but at positions in the papers which are not appropriate to turn over them if normal images are formed on the papers, the reverse image mode is set for forming a normal image of the document. Further, when a back face is printed in two-face copy mode, it is decided if the back face is placed on the platen so that the image in the back face is reproduced as a reversed image to the image in the front page according to document direction (portrait document or a landscape document), a position of margin, and a direction of the document with respect to document feed direction. The scan mode is changed when it is decided that the document is placed on the platen so that the image in the back face is reproduced as a reversed image to the image in the front page.
