Abstract
Disclosed is a method for the preparation of a seamless belt useful as the photosensitive element in an electrostatographic copying device. The method comprises: A. applying a film or soluble material over a mandrel; B. applying a photosensitive layer over the soluble film and heat treating the photosensitive layer; C. applying a layer of conductive material over the photosensitive layer; D. applying a seamless, heat shrinkable film of a thermoplastic resin over the layer of conductive material and heat shrinking the film to form a layered, endless belt; E. removing the layered belt from the mandrel; F. contacting the belt with a solvent for the soluble film to thereby dissolve the film; and G. turning the belt inside out to provide a belt having layers from the inside out of the seamless polymeric film, the conductive material and the photosensitive layer.
