Embodiment
As shown in Figure 1, development sleeve of the present invention comprises: sleeve body 11 and chuck portion 12.Wherein, chuck portion 12 is used to support magnetic roller 2, and chuck portion 12 is formed by the first end one extrusion modling of sleeve body 11.Chuck portion 11 has the through hole 12 that the end that supplies magnetic roller 2 passes, and offers the step groove 14 that is used for ccontaining bearing 4 at the place, aperture, outer end of through hole 13.
As shown in Figures 2 and 3, the outside surface in sleeve body 11 is formed with ripple struction 15.As shown in the figure, ripple struction 15 is made up of a plurality of cell bodies through the mould extrusion modling.The turning axle coaxial line of the cell body of the outside surface of sleeve body 11 and sleeve body 11, or with the turning axle of sleeve body 11 in angle of 45 degrees.
