A sheet-feeding device includes a sheet-feeding cassette with a sheet holding surface for holding a sheet. A side wall extends up from the sheet holding surface. A sheet-restricting plate is in the cassette on a downstream side in the sheet-feeding direction for setting a position of the sheet in a width direction perpendicular to the sheet-feeding direction. A cassette accommodating section accommodates the sheet-feeding cassette drawably in a direction parallel to the sheet-feeding direction. A projection is on an upstream side in the sheet-feeding direction from the position of the sheet-restricting plate. The projection is formed by partially projecting the side wall of the cassette upward. A height of the projection exceeds a maximum height of a sheet stack that can be accommodated in the cassette, and a height of parts of the side wall other than the projection is lower than the maximum height of the sheet stack.
