Abstract

Disclosed is a process for the formation of photoconductive cylindrical articles which comprises introducing into a cylindrical mold a fluid photoconductive material, spinning the mold about its axis at a speed sufficient to distribute the photoconductive material substantially uniformly along the inner surface of the mold, introducing into the cylindrical molds a fluid electrically conductive material, spinning the mold about its axis at a speed sufficient to distribute the electrically conductive material substantially uniformly along the inner surface of the mold, and causing the photoconductive material and the electrically conductive material to solidify, thereby forming a cylindrical imaging member having an electrically conductive layer and a photoconductive layer.

Disclosed is a process for the formation of photoconductive cylindrical articles which comprises introducing into a cylindrical mold a fluid photoconductive material, spinning the mold about its axis at a speed sufficient to distribute the photoconductive material substantially uniformly along the inner surface of the mold, introducing into the cylindrical molds a fluid electrically conductive material, spinning the mold about its axis at a speed sufficient to distribute the electrically conductive material substantially uniformly along the inner surface of the mold, and causing the photoconductive material and the electrically conductive material to solidify, thereby forming a cylindrical imaging member having an electrically conductive layer and a photoconductive layer.

The present process provides for preparing: photoconductive drums and belts suitable for electrophotographic imaging processes; multilayered photoconductive drums and belts having a high degree of uniformity in the thickness of the layers; multilayered photoconductive drums and belts wherein the outer or top layer has excellent surface finish characteristics; multilayered photoconductive drums and belts; multilayered photoconductive drums and belts having a high degree of dimensional uniformity; multilayered photoconductive drums and belts...
