Abstract
An automatic document feeder for use with an image forming apparatus, for conveying a document on a platen of the apparatus, includes a rotating conveyance belt for pressing the document to the platen thereby conveying the document along the platen; a pressing roller for applying pressure to the rotating conveyance belt and subsequently onto the document. The pressing roller includes a plurality of rows of rollers in a conveying direction of the document, and each of the plurality of rows is provided with a plurality of the pressing rollers. Tracks in an axis direction of the plurality of pressing rollers followed by at least two rows are different from each other, so that the tracks pass over different portions of the conveyance belt with respect to the conveying direction.
