The sheet contact member is contactable to the upper sheet container and the sheet in the lower sheet container. Either the upper sheet container or the sheet contact member has a sloped face inclined downward from downstream toward upstream in a container insertion direction, on at least one of a downstream side in the container insertion direction of a lower portion of the upper sheet container and an upstream side in the container insertion direction of an upper portion of the sheet contact member.
