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.

Abstract: A thin aluminum surface layer is formed on the outer peripheral surface of a tubular body of stainless steel material as a base layer to provide a fixing member. For forming the thin aluminum surface layer, arc thermal spraying apparatus is used such that material of a wire rod for thermal spraying is aluminum with purity of 99%, diameter of the wire rod is φ 1.2 mm, distance of thermal spraying is 120 mm, shifting velocity of the spraying gun is 20 mm/sec and air pressure is 0.5 MPa. Rotating the tubular body of stainless steel as a base layer at 150 rpm, thermal spraying of aluminum is performed with the spraying gun being shifted in the direction parallel to the axial direction of the tubular body of stainless steel as shown by the arrow. The thickness of the thermally sprayed aluminum surface layer is 20 to 30 μm.
