ABSTRACT:
An image-forming apparatus is adapted to make duplex copies with a separate pass through the fuser for each side. To prevent fusing oil from contaminating an image member by passage from a first image side of a duplex copy to a transfer drum and, hence, to the image member, an oiling algorithm to prevent or lessen oiling during fusing of the first side of duplex copies is provided. Preferably, the apparatus has a finite duplex return path which can hold a limited number of receiving sheets, which number is small enough that offset does not occur while doing first side-duplex fusing.
