Abstract
Abstract A plurality of identical images are formed in a single output image area in a partially superimposed relationship. The image data processing unit is provided with a memory unit for storing image data corresponding to the identical images. A reading signal generating unit generates a plurality of reading signals used for reading out the image data in the memory unit. Each of the reading signals provides information for an area in which one identical image is to be formed. A selecting unit selects one of the reading signals supplied by the reading signal generating unit. The selection being performed when the areas, in each of which one image is to be formed, the image being identical, are at least partially superimposed with each other. The memory unit outputs image data stored therein in accordance with the selected reading signal supplied by the selecting unit.
