ABSTRACT:
A both side recording apparatus for recording on both sides of a sheet of paper includes printer main body provided with an image forming device and a table provided with a feed-back path. In a one side print mode, a sheet of paper is fed from a cassette and it is temporarily halted by a registration roller, and then the sheet of paper is moved past a photosensitive drum to thereby have a toner image transferred from the drum to one side of the sheet of paper. Then, after having the toner image fixed to the sheet of paper, the sheet of paper is discharged onto a tray. In a both side print mode, after image fixing, the sheet of paper is routed to the feed-back path, so that the sheet of paper is inverted and again fed toward the registration roller. In accordance with the present invention, it is so structured that a sheet of paper is transported at an increased speed while being transported at least a part of the feed-back path.
