<p>An apparatus for printing both surfaces of a recording medium is capable of minimizing a blank space on the recording medium. The apparatus has a first image forming unit (4), disposed downstream in a carrying direction of the recording medium, for forming a toner image on one side of the recording medium; a second image forming unit (3), disposed upstream in the carrying direction of the recording medium, for forming the toner image on the other side of the recording medium; a fixing unit (5) for fixing the toner images onto both sides of the recording medium, and a control unit for controlling the first and second image forming units (4,3). The control unit controls, during single-sided printing, the first image forming unit (4) disposed downstream in the carrying direction. A distance between the fixing unit (5) and the first image forming unit (4) is short, and hence the blank space on the recording medium can be minimized. <IMAGE></p> |
