A stacking device which stacks a sheet includes a stacking unit on which the sheet is configured to be stacked, a regulating member, a moving member, and a restricting member. The regulating member is provided to be movable in a first direction and a second direction, which is a direction opposite to the first direction, and to regulate a position of the sheet stacked on the stacking unit. The moving member moves in a direction that is the same as a moving direction of the regulating member in accordance with the regulating member. The restricting member restricts movement of the moving member. So that the regulating member moves independently of the moving member, the restricting member restricts the movement of the moving member in a partial range of a range in which the regulating member moves.
