Abstract
An electrophotographic photosensitive member has a conductive support, and a charge generating layer and a charge transporting layer. The charge generating layer contains an acetal resin obtained from a reaction of polyvinyl alcohol, alkyl aldehyde having a structure shown in Formula (1) below, and aryl aldehyde having a structure shown in Formula (2) below: EQU R--CHO (1) wherein R is a substituted or unsubstituted, chain or cyclic alkyl group, and EQU Ar--CHO (2) wherein Ar is a substituted or unsubstituted aryl group. The electrophotographic photosensitive member is used in electrophotographic apparatus, device units and facsimile machines, while ensuring superior electrophotographic characteristics and an excellent image free from fog.
