  • Patent number: 5159391
    Abstract: An electrophotographic recording apparatus includes a photoconductive drum having a toner image developed on a surface of the drum, a transfer station having a transfer unit located above the photoconductive drum to transfer the toner image onto an underside surface of a paper moving along a predetermined path extending between the photoconductive drum and the transfer unit. The paper will be fed toward the transfer station in an upward orientation by feed rollers. Also, a fixing unit is provided along the path and downstream of a point of separation of the paper from the photoconductive drum, to fix the toner image onto the paper with the recorded surface facing down when the paper is ejected from the transfer station, and a guide for smoothly guiding the leading end of the paper into an entrance of the fixing unit.
