PHOTOCONDUCTIVE BODY USING SENSITIZED EXTRINSIC PHOTO-PRODUCTION PIGMENT

摘要

PURPOSE: To use an extrinsic pigment charge producing layer and a polymer charge transfer layer such as PVK by constituting a base body, an extrinsic pigment layer and a charge transfer layer containing a charge transfer polymer layer. ;CONSTITUTION: The photoconductive body contains a base body 10, a layer 13 to sensltize layers, an extrinsic pigment charge producing layer 14 in contact with the layer 13, and a charge transfer layer 16 in contact with the pigment charge producing layer 14. In this method, the base body 10 is composed of opaque or substantially transparent, and if necessary, may contain various kinds of proper conductive or nonconductive material having mechanical characteristics. Further, the charge transfer layer 16 contains charge transfer small molecules dispersed or dissolved in an inactive film forming binder polymer such as polycarbonate. The charge transfer layer 16 is preferably formed of a charge transfer polymer containing a charge transfer part dispersed in a film forming polymer.;COPYRIGHT: (C)1994,JPO
