Abstract

PURPOSE:To suppress rise of residual potential, to obtain a stable electric characteristics, and to prevent spotted abnormal images and background stains by incorporating a halogenated phthalocyanine compound in an interlayer. CONSTITUTION:The electrophotographic sensitive body is formed by successively laminating on a conductive base body the interlayer containing the halogenated phthalocyanine compound, such as a halogenated compound such as brominated or chlorinated, of metal-free or metal-phthalocyanine, an electric charge generating layer, and a charge transfer layer, thus permitting rise of residual potential to be suppressed, stable electric characteristics to be obtained even against changes of environmental conditions, such as temperature and humidity, and the obtained image to be prevented from abnormal spots and background stains, and enhanced in reliability.
