Abstract

An apparatus suitable for fabricating a substrate suitable for photoconductive members has a cylindrical rotating vessel surrounded by a housing which contains a plurality of rigid spheres therein. A substrate supporting means is placed within the cylindrical rotating vessel so as to be rotatable coaxially therewith. A supplying means for a surface coating liquid, such as polybutene, is placed at an upper position over the external wall face of the cylindrical rotating vessel. A reservoir for the surface coating liquid is placed at a lower position below the external wall face of the cylindrical rotating vessel. A means to circulate the surface coating liquid to the supplying means is employed.
