A first reversing inlet path and a second reversing inlet path are branched from a path for transporting a sheet having an image formed thereon by a printer unit. A first reversing path and a second reversing path are connected respectively to the first reversing inlet path and the second reversing inlet path. The sheet having the image formed thereon by the printer unit is transported through the first reversing inlet path or the second reversing inlet path for reversing the sheet. When one of the first reversing inlet path and the second reversing inlet path is unusable, the sheet reversing operation is continued using the other reversing inlet path.

1. Field of the Invention
The present invention relates to an image forming apparatus that functions to form images on both sides of a sheet.
2. Description of the Related Art
FIG. 1 is a schematic overall view of a copying machine as one example of an image forming apparatus according to a first embodiment of the present invention.
FIG. 2 illustrates a construction of a duplex feed mechanism in the copying machine.
FIGS. 3A to 3C are a first set of illustrations for explaining a sheet flow when a sheet is re-fed to an image forming section using the duplex feed mechanism.
Preferred embodiments of the present invention will be described below with reference to the drawings.
(First Embodiment)
FIG. 1 is a schematic overall view of a copying machine as one example of an image forming apparatus according to a first embodiment of the present invention. Note that the image forming apparatus embodying the present invention is not limited to a copying machine, but it may be embodied as a facsimile machine, a printer, a composite machine, etc. Further, a sheet as used herein is not only a piece of plain paper, but may also be a thin resin sheet, a postcard, a piece of cardboard, an envelop, a plastic thin sheet, etc. which are used instead of plain paper.
