Abstract
The invention relates to a method and apparatus for forming images on both sides or surfaces of sheets corresponding to images on two-side originals. In a method for two-side image formation for forming images on both sides of sheets from images formed on two-side originals, a first-side image formation cycle is continuously performed for a required number of sets of sheets, the first-side image formation cycle including sequential operations for forming images on the first sides of the originals on the first sides of the sheets and for storing the one-side copied sheets in an intermediate storing portion, and thereafter a second-side image formation cycle is performed by sequentially forming images of the second sides of the originals on the second sides of the corresponding sheets. The invention also relates to an apparatus adopting this method.
