Abstract

An image forming apparatus of the present invention includes a printer engine for forming an image on a paper sheet fed from a paper cassette. A paper feeder feeds the paper sheet from the paper cassette to the printer engine while separating it from the other paper sheets stacked on the cassette. A switchback path branches off the transport path of the paper feeder for temporarily storing the paper sheet fed from the paper cassette. The paper sheet fed from the paper cassette enters the switchback path with its leading edge at the head. A roller pair is positioned on the switchback path for switching back the paper sheet received in the switchback path such that the paper sheet leaves the switchback path toward the printer engine with its trailing edge at the head.
