Abstract
A discharge device which discharges a sheet includes: a driving shaft which is driven to rotate by a driving source; a plurality of driving rotating members which is provided on the driving shaft; a rotating member which is provided on the driving shaft, has a larger outside diameter than an outside diameter of the driving rotating member, is formed by joining at least two divided components, and includes stepped portions that protrude, to a larger extent, in a radial direction in boundary portions of the at least two components on upstream sides of a rotation direction of the rotating member than on downstream sides thereof; and follower rotating members which are pressed against the driving rotating members.

1-6. (canceled)
A discharge device which discharges a sheet, comprising:
- a shaft;
- and
- a rotating member provided on the shaft, the rotating member being rotatable with respect to the shaft and including a first rotating part and a second rotating part,
- wherein, when the rotating member is viewed in an axial direction of the shaft, a distance between a rotation center of the shaft and a downstream edge portion of the first rotating part in a rotating direction of the rotating member is greater than a distance between the rotation center of the shaft and an upstream edge portion of the second rotating part in the rotating direction,
- wherein the downstream edge portion of the first rotating part adjoins the upstream edge portion of the second rotating part in the rotating direction, and
- wherein a circumferential surface of the rotating member does not have a protruding portion or a recessed portion except for a vicinity of a border area between the first rotating part and the second rotating part.
