Abstract: Provided is a fixing sleeve making it possible to reduce the surface roughness of the inner circumferential surface of the fixing sleeve by spinning, and a method for manufacturing the fixing sleeve. The spinning is performed by moving rollers, in the axial direction of a cup-shaped tubular body and, at the same time, a burnishing tool (spherical tool) is pressed against the outer circumferential surface of the cup-shaped tubular body after the spinning, and the burnishing tool is moved in the same direction as the rollers. The cup-shaped tubular body is plastically deformed in the axial direction of the cup-shaped tubular body, reduced in wall thickness, and elongated in the axial direction.
