<p>A double-sided image forming device comprises a double-side operation unit (13). The double-side operation unit (13) includes a sheet reversing unit (1, 2, 3) including a switchback conveying path (2) for reversing a front side and a back side of a sheet conveyed from an image forming unit, and a reconveying path (5) for reconveying the sheet to the image forming unit so as to form an image on the back side. The switchback conveying path (2) has a length (L) smaller than a length (L Pmax) of a conveyable maximum-size sheet. The double-side operation unit (13) can slide from/toward a body of the double-sided image forming device in a direction perpendicular to a direction of conveying the sheet. A rear end guide (9) is further provided in the switchback conveying path (2) so as to guide a rear end of a large-size sheet. <IMAGE></p> |
