ABSTRACT:
An image forming apparatus for duplex printing has a duplex printing unit conveying the paper sheet, which is printed on a first side by a developing unit and a fixing unit on a first paper conveyance path and then conveyed to the paper discharge unit, to be fed back to the developing unit through the fixing unit to form another image on a non-printed side of the paper sheet. The duplex printing unit includes an auxiliary conveyance guide disposed on a surface of the paper conveyance guide to define a second paper conveyance path with the surface of the paper conveyance guide, the second paper conveyance path for conveying the paper sheet printed on the first side and conveyed to the paper discharging unit to be fed back to the developing unit in a reversed posture, a reverse conveying roller assembly disposed between the surface of the paper conveyance guide and the auxiliary conveyance guide to convey the paper sheet through the second paper conveyance path, and a paper conveying portion formed at a point where the first paper conveyance path and the second paper conveyance path meet, to convey the paper sheet picked up by the pickup unit and the paper sheet conveyed through the reverse roller assembly to the first paper conveyance path. Accordingly, the image forming apparatus for duplex printing can have a paper conveyance path with a reduced number of parts as well as a simpler structure.
