Abstract
A sheet feeder includes a sheet tray, a feed roller, a separating pad, a feed motor, a conveying roller pair, and a deformation prevention member. The feed roller picks up and feeds first and second sheets from the sheet tray. The separating pad separates the first sheet from the second sheet together with the feed roller. The deformation prevention member is provided to prevent deformation of a head of the second sheet caused by the feed roller and the separating pad nipping the second sheet.
