ABSTRACT:
As a charge transport material for a charge transport layer of an electrophotographic photosensitive material, a poly-2,3-epoxypropyl carbazole compound is used together with a specific hydrazone compound and/or a specific butadiene compound. Film-formation property and adhesive property of the charge transport layer are much improved thereby to enable use of a photoconductive material in a higher concentration.
