LAMINATE TYPE ELECTROPHOTOGRAPHIC SENSITIVE BODY AND ELECTROPHOTOGRAPHIC METHOD

摘要

PURPOSE:To reduce the optical memory and electrostatic charge memory of a laminate type sensitive body by incorporating a binder having a specified dielectric constant into the charge transferring layer of the sensitive body. CONSTITUTION:A binder resin having =3 dielectric constant is incorporated into the charge transferring layer of a sensitive body having a charge generating layer and the charge transferring layer. Polystyrene, polymethyl acrylate, PVC, polyvinylidene chloride, polyethylene or other homopolymer, a mixture thereof or a copolymer is used as the resin having =3 dielectric constant. The resin can prevent more effectively carrier trap than a resin having =3 dielectric constant. The resulting sensitive body is applicable to an electrophotographic method in which a stage including electrostatic charge and exposure is repeated at least twice.
