ABSTRACT:
In a double-sided image forming apparatus and method, back-side images are developed on a first middle transfer belt prior to developing of front-side images on the first middle transfer belt, and the back-side images are transferred to a second middle transfer belt. The number of back-side images allowed to be supported at a time on the second middle transfer belt is determined. The number of back-side images are developed on the first middle transfer belt prior to developing of the same number of front-side images on the first middle transfer belt. The front-side image of the first middle transfer belt and the back-side image of the second middle transfer belt are simultaneously formed on both sides of a copy sheet.
