Abstract
Abstract Laminated flexible photoreceptors exemplified by a core or base, a resilient elastomer layer covering the core or base, a shrunk resin film in compressive external contact with the elastomer layer, a charge conductive layer applied to the resin film and a photoconductive layer in blocking contact with the charge conductive layer. The photoreceptors are of generally improved quality producing fewer streaks or spots and with less charge migration in uniform solid areas.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
72 words
A method of liquid development of electrostatic latent images which comprises moving into developing contact a resilient photoreceptor bearing a latent electrostatic image and a rigid liquid applicator carrying liquid developer, said photoreceptor having a resilient surfaced base, a shrunk polymeric film in compressive contact with said base, a layer of conductive material over said film, and a layer of less than about 80 microns of photoconductive material overlying the conductive material.
Claim 2
Independent Claim
72 words
A method of liquid development of electrostatic latent images which comprises moving into developing contact a resilient photoreceptor bearing a latent electrostatic image and a rigid liquid applicator carrying liquid developer, said photoreceptor having a resilient surfaced base, a shrunk polymeric film in compressive contact with said base, a layer of conductive material over said film, and a layer of less than about 80 microns of photoconductive material overlying the conductive material.
Claim 3
Dependent Claim
