Abstract
An image forming apparatus includes a paper transport apparatus having a paper supply path, a paper supply tray, and an invert-transport path for alternately transporting blank copy paper sheets and single-face copy paper sheets. The invert-transport path includes an inversion path, a double-face-copy invertor apparatus, and a double-face-copy transport path member. The invert-transport path is connected via the double-face-copy transport path member to the paper supply path, and the paper supply tray is coupled to the double-face-copy transport path member. The single-face copy paper sheets are fed from the paper supply tray via the double-face-copy transport path member to the paper supply path. The paper transport apparatus further includes a control unit for performing a first operation and a second operation. The first operation is carried out in such a manner that, when a paper jam occurs in the invert-transport path, a first single-face copy paper sheet located at an image transfer unit of the image forming apparatus is formed as a double face copy paper sheet and then is directly ejected to an ejection tray. The second operation is carried out in such a manner that a second single-face copy paper sheet is sequentially advanced to a waiting position located on an up stream side of the paper jam.
