ABSTRACT:
An erasure portion designation section designates position data corresponding to an arbitrary portion to be erased, which is not required to be copied, of the original placed on the original table. A memory stores the position data of the portion to be erased designated by the erasure portion designation section. The position data is stored in units of originals for a plurality of originals. A readout designation section designates the position data, corresponding to the portion to be copied of a plurality of originals stored in the memory, to be read out in correspondence with the original to be copied. An original scanning section optically scans the original to be copied placed on the original table to obtain an optical image. An image forming section receives the optical image obtained by the original scanning section and transfers an image corresponding to the optical image onto an image recording medium. An image erasure section receives the position data of the portion to be erased read out from the memory by the readout designation section and erases a corresponding portion of the image to be formed by the image forming section.
