Abstract
Abstract A method of surface-processing a photoreceptor base including aluminum material for electrophotography on a lathe, in which a surface of the base is cut by a cutting tool having a sintered polycrystalline diamond body while cutting fluid, composed of water, an aqueous solution of a surface-active agent or an aqueous solution of a water-soluble organic solvent, is being supplied to the surface of the base frame.
