Abstract
Disclosed is an improved process for the preparation of an electrostatographic photoreceptor which comprises: A. preparing a free-standing film of an unoriented, organic, active transport material by solvent coating the material onto a non-adherent base and removing at least part of the solvent; B. detaching the film from the base; C. annealing the film above its glass transition temperature to provide a film free of strains; D. vapor depositing a film of a photoconductive material onto the organic film; and E. attaching the film of photoconductive material at its exposed surface to a conductive substrate with an adhesive material.
