摘要

An electrophotographic photosensitive member has a support and a photosensitive layer provided on the support. The photosensitive layer containing a polysilane compound which has a stractural unit represented by the following Formula (1) and has as a terminal group of the polymer chain a group selected from the group consisting of hydroxy, alkoxy and aryloxy <CHEM> wherein R1 represents a hydrogen atom, an alkyl group or an aralkyl group; R2 represents an ethyl group, a cycloalkyl group, a vinyl group, or an alkyl group or unsaturated hydrocarbon group having 3 or more carbon atoms, whose carbon atom directly bonded to the phenyl group is a primary carbon atom or a secondary carbon atom.
