Image forming apparatus having synthetic recording functions
 There is an image forming apparatus in which images of a plurality of originals set on the original plate glass are individually exposed, scanned and read, and the read images are synthesized and recorded at arbitrary positions on a recording paper. This apparatus also has a device to record the images on the front and back surfaces of the recording paper. The synthetic recording and the front and back surface recording can be arbitrarily switched and selected. This apparatus is provided with a trimming function to erase unnecessary image portions of the images, a masking function to prevent the shaded portions from being recorded on an paper, and the image shift function to adjust the synthesizing positions of the images on the recording paper for every image. In the serial page copy mode adapted for book images, the masking function is automatically selected and the recording positions on the front and back surfaces of the recording paper are aligned to either one of the right and left sides of the paper, so that the binding margins can be secured on one selected side of the paper. The masking function is released when the serial page copy mode is released.
