Abstract

PURPOSE:To obtain an electrophotographic receptor low in remaining potential and god in sensitivity, by using a specified disazo pigment as a charge generating material. CONSTITUTION:The disazo pigment to be used as a charge generating material has a benzoxazole ring represented by the formulaI in which A is an aromatic coupler and B is H, Cl, or methyl, and it is a compound, such as the formula II. Said disazo pigment, preferably having <=5 micrometer particle diameter, is dispersed into a binder solution, this solution is coated on a conductive layer, such as an aluminum plate to form a <=5 micrometer thick charge generating layer, and on this layer, a 5-30 micrometer thick charge transfer layer containing a charge transfer substance, such as pyrazolines is formed, and the desired electrophotographic receptor is thus obtained.
