A discharge unit is disposed downstream of a principal transport path of a compound machine, and a shifter function is provided in this discharge unit. By shifting the paper passage position relative to a photosensitive drum when printing the front side and the paper passage position relative to the photosensitive drum when printing the back side, the region in which the surface electric potential of the photosensitive drum increases is diminished, and the region in which photographic fog is generated is made smaller. Thus, when printing the second and subsequent sheets, even when a slight amount of displacement of the transport position of the recording paper occurs, it is possible to suppress that recording paper making contact in the photographic fog region on the photosensitive drum, and defective printing can be prevented.
An image forming apparatus that has a duplex printing function, wherein while transporting a recording medium, after recording an image formed on an image carrier to a first side of the recording medium, this recording medium is re-transported towards the image carrier and an image formed on the image carrier is recorded on a second side of this recording medium that differs from the first side, the image forming apparatus comprising:
