Abstract
A sheet feeding apparatus for reconveying copy paper sheets carrying an image to a transfer section by suction. Along the transport path to the apparatus is arranged a curl inducing mechanism that induces curls in the copy paper sheets, whereby the copy paper sheets with upwardly curled edges are loaded in the apparatus. With this arrangement, the copy paper sheets are surely separated by injecting air, thereby preventing multi-feeds.
