ABSTRACT:
An image formation apparatus capable of scanning using an optical scanning unit in both directions of a sub-scanning operation, performing a predetermined image processing on the information read by a CCD, and subsequently storing in a page memory. CPU controls address count of the main scanning address counter and sub-scanning address counter to prevent the image whose output image to the printer is in the reversing direction becomes a mirror image. Accordingly, it is possible to provide an image formation apparatus capable of outputting an appropriate image signal regardless of the direction in the sub-scanning direction of the optical scanning unit, and processing successive duplication at a high speed.
