ABSTRACT:
An image forming apparatus capable of incorporating a DF, an ADF or an RDF includes a digitizer for designating at least one area of an original, an image forming unit for forming an original image of the designated area on a transfer sheet, and a control section for adding a specific image to the designated area. The control section also allows a multi-copy or a two-sided copy operation for a plurality of designated areas with different colors. The apparatus also includes a memory, the area designation data of which is retained whether reset by a reset key or upon a power ON operation. In this case, only the designated areas are reset. The apparatus further includes a middle tray and a second sheet feeder, which are selectively used according to the types of sheets.
