摘要： 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.

摘要： An electrophotographic image forming apparatus includes an electrostatic latent image carrying body, an electrifying unit for electrifying the image carrying body, a light irradiating unit to form an electrostatic latent image in accordance to image information, a developing unit for discharging toner to the image carrying body to develop the latent image, a transfer unit for transferring the toner image to a recording sheet, and a cleaner for removing residual toner on the image carrying body. The toner removed from the image carrying body is recirculated to the developer receiving box. An additional toner image is formed on a position other than a first position where the electrostatic latent image is formed in accordance with the image information. The toner is removed by the cleaner without being transferred to the recording sheet and recirculated from the image carrying body to the developer receiving box.
