PURPOSE:To obtain an electric charge generating material capable of generating carriers by exposure to the visible light and forming a superior film by incorporating the charge generating material made of a chain polymer having specified rhodanine derivatives on its side chains and an electric charge transfer material in the same single layer. CONSTITUTION:The chain polymer to be used as the charge generating material has on its side chains the rhodanine derivatives represented by formula I in which R1 is OH or 1-6C lower alkyl, and it is added in combination with the charge transfer material to the single photosensitive layer or this charge transfer material is mutually dissolved with a binder resin or dispersed into the binder resin to form the charge transfer layer and it is combined with the charge generating layer to form the laminated composite photosensitive layer. This charge generating polymer is allowed to generate carriers by exposure to the visible light and this material itself is superior in film forming performance as well as light transmittance and stability. |
