Abstract
An apparatus for producing a substrate having a surface with a plurality of spherical dimples suitable for light receiving members including: a cylindrical rotating vessel having an external wall face and an inner wall face surrounded by housing, a rotating vessel containing a plurality of freely movable rigid spheres therein to surface treat the substrate, the cylindrical rotating vessel having a plurality of perforations through which the smooth passage of a surface coating liquid is effected; a substrate support means placed within the cylindrical rotating vessel so as to be rotatable coaxially therewith; a spouting device for spouting the surface coating liquid through the plurality of perforations into the cylindrical rotating vessel, the spouting device is placed crosswise in the circular space circumscribed by the inner wall of the housing and the external wall face of the cylindrical rotating vessel in a horizontal plane to the central axis of the cylindrical rotating vessel; a storing tank for the surface coating liquid; and device for circulating the surface coating liquid to the spouting device.
