Abstract
Abstract An image forming apparatus (10) provided with a post-processing device in a sorter (14) for performing a post-processing on an image-formed sheet includes a unit (11) for reading an image of an original, a unit (12) for forming an image data read by the reading unit (11) on a sheet of paper by performing a predetermined processing on the read image data, and a unit for controlling a direction of the image data to be formed on the sheet of paper for performing the post-processing done by the post-processing device at a specified place of the image-formed sheet of paper. First a mark on a leading sheet is scanned to find out where a staple is to be placed. After the original scanning by a CCD element, the image processing controller decides if it is necessary to rotate the digital image to accomplish that the stapler will be able to put a staple at the defined position. Optionally the post-processing consists in punching.
