ELECTROPHOTOGRAPHIC PHOTORECEPTOR CONTAINING NAPHTHALENETETRACARBOXYLIC ACID DIIMIDE DERIVATIVES AS ELECTRON TRANSPORT MATERIALS IN A CHARGE GENERATING LAYER AND ELECTROPHOTOGRAPHIC IMAGING APPARATUS EMPLOYING THE SAME

摘要

A double layered electrophotographic photoreceptor including conductive supporting base, charge generation layer and charge transfer layer is provided to represent excellent electrostatic property such as high photosensitivity and less light exposure potential features by comprising naphthalene tetracarboxylic acid diimide derivative in the charge generation layer as electron transfer material. The electrophotographic photoreceptor includes a conductive supporting base, a charge generation layer and a charge transfer layer on the supporting base. The charge generation layer comprises naphthalene tetracarboxylic acid diimide derivative represented by the formula(1), wherein R1 and R2 are independently hydrogen, halogen group, substituted or non-substituted alkyl group including carbon atoms ranging from 1 to 20, substituted or non-substituted alkoxy group including carbon atoms ranging from 1 to 20; R3 is substituted or non-substituted alkyl group including carbon atoms ranging from 1 to 20, substituted or non-substituted alkoxy group including carbon atoms ranging from 1 to 20, substituted or non-substituted aralkyl group including carbon atoms ranging from 7 to 30 or -(CH2)N-Y-R4 group; AR is substituted or non-substituted aryl group including carbon atoms ranging from 6 to 30; Y is oxygen, sulfur or NH; R4 is hydrogen, or substituted or non-substituted alkyl group including carbon atoms ranging from 1 to 20; and N is integer of 1 to 12.
