US 2006/0125172 A1 · Paper feeder and image forming apparatus

Abstract

A paper feeder includes a paper storing section that stores papers by vertically stacking the papers on a loading plate, and the uppermost paper stored in the paper storing section is fed by a pickup roller. In order to transport a supplied paper to an image forming apparatus without changing its posture, paper outgoing apertures are individually disposed on the paper feeder side. Transfer paths, respectively corresponding to the paper outgoing aperture, are disposed in the image forming apparatus, and a paper supplied from the paper feeder is transported to an image formation processing section of the image forming apparatus. This allows a paper to be transported without being curved, when the paper is supplied to the image forming apparatus from an additionally provided paper feeder. As a result, paper jam is prevented.
