The sheet container loads multiple sheets. The sheet feeder feeds a sheet out of the multiple sheets in the sheet container. The separator separates the sheet from another sheet fed together with the sheet. The guide having a guide surface to guide the sheet passing the separator such that the sheet is fed in a predetermined sheet conveying direction. An upstream end in the sheet conveying direction of the guide surface of the guide is located lower than a downstream end in the sheet conveying direction of the separator. The projection is disposed facing the separator at the upstream end in the sheet conveying direction of the guide surface.
