Abstract
An image forming apparatus with image forming area selection. An original table receives a light-transparent original document such that an original image surface selectively faces upward or downward. A light source transmits light through the original while the light source is moved with respect to the original. An erasure area specifying means specifies an erasure area portion of the original document image surface while the light source is moving. An erasure area storage means stores position data of the erasure area specified by the erasure area specifying means. An original scanning means, having an optical system moved along the original table, scans the original while the original faces downward. An image forming means focuses light emitted from the original scanning means and reflected by the original and develops an image on an image forming medium to form an image. An image erasing means selectively erases an image formed by the image forming means. Control means reads out the position data corresponding to the erasure area from the erasure area storage means at any time during the operation of the image forming means and supplies the position data to the image erasing means.
