Positively-chargeable single-layered type electrophotographic photoconductor

A positively-chargeable single-layered type organic electrophotographic photoconductor comprising an electroconductive support and an organic single-layered photoconductive layer comprising a charge generating material, an organic positive hole transporting material and an organic acceptor compound which are dispersed in a matrix binder agent, with the relationship of the oxidation potential (E.sub.ox) of said charge generating material.ltoreq.the oxidation potential (E.sub.ox) of said organic positive hole transporting material being satisfied,

• wherein the relationship of the reduction potential (E.sub.red) of said charge generating material.ltoreq.the reduction potential (E.sub.red) of said organic acceptor compound is satisfied, and
• said charge generating material is a p-type (positive-type) azo pigment.
