ABSTRACT:
A sheet material transporting apparatus has a first convey portion for conveying a sheet having an image on one surface thereof in a first direction along a first convey path, the image being formed by an image-forming section, and a second convey portion for conveying the sheet in a second direction along a second convey path extending to the image-forming section through the first convey path so as to form an image on the other surface of the sheet. A trailing edge detector is arranged in the vicinity of a branched portion between the first and second convey path to detect the trailing edge of the sheet. In a sheet guide portion for causing the branched portion between the first and second convey paths to communicate with the discharge portion, the sheet is sent in a first direction for a predetermined period of time after the trailing edge of the sheet is detected by the trailing edge detector to invert the sheet conveying direction to the second convey path.
