Abstract

PURPOSE:To form an electrophotographic receptor high in sensitivity and superior in durability, by using a specified disazo pigment as a photoconductor. CONSTITUTION:A disazo pigment, such as shown by the formula II, represented by the general formulaIin which A is an aromatic coupler, and B is an optionally substituted phenylene or naphthalene group is used. When needed, a 0.1-5mum thick adhesive layer is provided on a conductive layer, such as an aluminum plate or paper treated to enhance conductivity, said disazo pigment smaller than about 5mum in size dispersed into a binder is coated on this layer to form a charge generating layer smaller than about 5mum in thickness, and further on this layer, a charge transfer material, such as tetracyanoethylene or N-ethylcarbazole dispersed into a binder is coated to form a 5-30mum thick charge transfer layer for use in an electrophotographic receptor.
