Electrophtographic organic receptor

Abstract

Abstract PURPOSE:To obtain superior characteristics of each of exposure sensitivity, wavelength, and deterioration resistance, by using a charge transfer layer made of a specified polyester, and a charge generating layers made of crystalline oxytitanium-phthalocyanine. CONSTITUTION:The charge transfer layer contains as a charge transfer agent an effective polyester component obtained from at least 80mol% 2,6-dimethoxy-9,10- dihydroxyanthracene of all the dihydroxy components, and at least 80mol% alpha,omega- dicarboxylic acid of all the dicarboxylic acids. The charge generating layer contains crystalline oxytitanium phthalocyanie as an effective component. Both layers are formed on a conductive substrate in the order to the charge generating and transfer layers. A barrier layer may be formed between the charge generating layer and the substrate in order to prevent lowering of charged voltage.
