ABSTRACT:
In forming a first image and a second image on both sides of a recording paper by using an electrophotographic process, the first image is generated on a photosensitive drum, and is transferred to an intermediate transfer belt which can transfer and hold a developer image. The photosensitive drum and the intermediate transfer belt is disposed across a plane where the recording paper is conveyed. Subsequently, the second image is generated on the photosensitive drum after a developer remaining thereon has been removed, and is transferred to one side of the recording paper. After the second image has been fixed on one side of the recording paper, the first image is transferred from the intermediate transfer belt to the other side of the recording paper and fixed.
