Image forming apparatus and image forming method using the same for duplex printing |
摘要 |
<p>An image forming apparatus and an image forming method using the same. The image forming apparatus includes a discharge unit which has a driving roller rotating in forward and reverse directions and first and second driven rollers engaged with the driving roller to rotate together therewith, a duplex print unit which feeds the paper again to a developing unit so that the paper printed on a first surface is subsequently printed on a second surface, and a control unit which controls a rotational direction of the driving roller so as to move a first sheet of paper between the driving roller and the first driven roller and move a second sheet of paper between the driving roller and the second driven roller. Accordingly, the image forming apparatus is capable of controlling the forward movement of the second sheet of paper without interference with the reverse movement of the first sheet of paper, thereby decreasing a time required to perform duplex printing.</p> |
