PURPOSE:To obtain an electrophotographic receptor having high sensitivity over the entire visible region and superior durability by using respectively specific disazo dye and distyrylbenzene compound, and contg. the former dye in an electric charge generating layer and the latter in an electric transfer layer. CONSTITUTION:The diazo dye expressed by the formula (1) is contained at 10-100wt% of an electric charge generating layer 22, whereby the layer 22 of 0.01-5mu thicknesses is formed on a conductive substrate 11. Next, an electric charge transfer layer 33 of 5-40mu thicknesses contg. 10-80wt% the compound expressed by the formula (2)[R is carbazolyl, pyridyl, thienyl, indolyl, furyl, or respectively (un)saturated phenyl, styryl, naphthyl, anthryl; substituents are dialkylamino, alkyl, alkoxy, COOH or its ester, halogen CN, aralkyl, NH2, OH, NO2 and acetylamino]is formed. In this way, the photosensitivity, durability, etc. are improved. |
