发明名称 Image forming apparatus with a two-sides image forming operation
摘要 An image forming apparatus operable in a duplex image transfer mode of the present invention stores image data to be transferred and transfers the image data to a recording medium at an image forming section. In the duplex image transfer mode, a reversing section reverses a paper sheet or similar recording medium passed the image forming section and again delivers it to the image forming section. When image data does not have to be transferred to the rear side of the last paper sheet, the last paper sheet carrying an image on its front side is driven out of the apparatus from the halfway point of a reversal path via an outlet path without the intermediary of the image forming section. The apparatus successfully reduces the conveying time.
