A digital copier for reducing images printed on a plurality of documents and reproducing the reduced images on a single paper sheet in a desired arrangement. An image forming timing of a scanner and a paper transporting timing of a register roller pair are set up constantly with accuracy by determining a period of time needed for a scanner to move from its original position or home position to a predetermined position and, on the basis of the determined period of time, automatically correcting a variation in the next image forming timing which is ascribable to a change of magnification, for example.
