ABSTRACT:
The present invention provides an electrophotographic sensitive element which comprises an electroconductive support and a photosensitive layer formed thereon and containing some charge-carrier generating pigment and a specific charge transfer substance. Said specific charge transfer substance is just a substance selected from well-known photoconductive substances, but when it is applied in combination with a charge-carrier generating pigment, it renders a photosensitive element having a remarkably improved sensitivity.
