Abstract
PURPOSE: To raise the sensitivity of an electrophotographic photosensitive material combined with a charge generating substance, by using a specific charge transfer substance.
CONSTITUTION: A charge generating layer containing the charge generating substance as main constituent and having a thickness of about 5 μm (20 μm if the layer is the uppermost) and a charge transfer layer having a thickness of about 10 to 100 μm and containing as main constituent the charge transfer substance represented by the formula where R1 and R2 denote hydrogen, alkyl, aralkyl or aryl are provided on an electroconductive substrate. Otherwise, a charge generating substance having an average grain size preferably not more than about 0.1μ is dispersed in a mixture consisting of a binder and said charge transfer substance and the mixture is then coated on an electroconductive substrate so that a photosensitive layer is produced at a thickness of about 3 to 100 μm.
