    摘要: A sheet stacking device includes a pair of first sheet stackers, a pair of sheet alignment members, a second sheet stacker, a sheet removal portion, and control circuitry. The first sheet stackers stack both end portions of a sheet in a direction orthogonal to a sheet ejecting direction. The sheet alignment members contact both ends of the sheet in the orthogonal direction to align the sheet on the first sheet stackers. The second sheet stacker is disposed lower than the first sheet stackers and stacks the sheet dropped from between the first sheet stackers. The sheet removal portion is disposed on one side in the orthogonal direction. The control circuitry causes one of the first sheet stackers and one of the sheet alignment members to move toward an opposite side of the sheet removal portion in the orthogonal direction after the sheet is dropped from between the first sheet stackers.
