ABSTRACT:
An endless belt shaped electrophotographic photoconductor is disclosed, which comprises an electroconductive support material, a photoconductive layer formed thereon, a joint portion by which the electrophotographic photoconductor is worked into the shape of an endless belt, and a grounding electrode which is electrically connected to the electroconductive support material, the joint portion comprising an electroconductive overcoating layer by which the photoconductive layer in the joint portion is covered, the electroconductive overcoating layer comprising a polymeric material having a glass transition of -10.degree. C. or lower and finely-divided electroconductive particles, or the joint portion further comprising a joint reinforcement resin layer which is formed so as to be inserted between the electroconductive overcoating layer and the photoconductive layer in the joint portion.
