Abstract
A recording-medium ejecting device includes a first rotating member that rotates and a second rotating member that faces the first rotating member and that is rotated by rotation of the first rotating member. At least one of the first rotating member or the second rotating member is provided with projections and recesses at both ends thereof. The projections and recesses are alternately arranged in a circumferential direction. The projections extend continuously from a rotating member body in an axial direction and have a diameter greater than that of the rotating member body. The recesses extend continuously from the rotating member body in the axial direction and have a diameter smaller than that of the rotating member body. The projections at one end of the rotating member body and the projections at the other end of the rotating member body are at the same positions in a circumferential direction.
