Abstract
Abstract When images on the front and rear sides of multiple originals are reduced in size and recorded onto both sides of a single recording sheet in composite form, recording positions of images on the front and rear sides of each original are determined such that reduced images on the front side of the original are recorded on the front side of the recording sheet and reduced images on the rear side of the same original are recorded at corresponding positions on the rear side of the recording sheet. As a result, when the recording sheet is cut into pieces corresponding to respective recorded images, images on the front and rear sides of each cut piece of the recording sheet respectively agree with images on the front and rear sides of each original.
