A conveying device includes: a rotating body that rotates; a belt that contacts the rotating body and rotates; a restricting member that is disposed at each of the two rotation axis direction side edges of the belt, positions the side edges of the belt, and restricts movement of the belt in the rotation axis direction; a lubrication agent that is supplied to the inner peripheral face of the belt; and a slide bearing that is disposed so as to overlap in the rotation axis direction with the restricting member when viewed along a rotating body radial direction, the slide bearing being open to the belt side and rotatably supporting the rotating body.
