APPARATUS, METHOD AND SYSTEM FOR FORMING IMAGE, AND MEDIUM

摘要

PROBLEM TO BE SOLVED: To prevent a plurality of sheets from colliding even if a processing state is changed in the middle of continuous processes of a series of image formation to the sheets. SOLUTION: At least when a sheet reverse delivery mode is changed to a straight delivery (a non reverse delivery) mode, a start timing (an image formation interval) of an image formation operation to the first sheet related to the straight delivery mode is delayed from a start timing of a normal image formation operation in the straight delivery mode, so that the image formation interval is extended.
