Abstract

A document feeder includes a sheet tray loaded with sheets stacked thereon in a predetermined direction, a pickup unit pulling in sheets on the sheet tray and feed the sheets, a separation unit that separates a sheet from the sheets fed through the pickup unit and feeds the separated sheet, so as to convey the sheets sequentially on a sheet-by-sheet basis, and a guide unit that forms a carrying path extending from the sheet tray to the separation unit. The guide unit has an entrance portion provided at a side of the sheet tray relative to the separation unit, as an entrance of the sheets on the sheet tray into the carrying path. The carrying path has a longer length in the predetermined direction at a downstream side in a sheet carrying direction relative to the entrance portion than a length in the predetermined direction of the entrance portion.
