    摘要： An electrophotographic photoreceptor includes a pyridine-substituted asymmetric naphthalenetetracarboxylic acid diimide derivative. The pyridine-substituted asymmetric naphthalenetetracarboxylic acid diimide derivative has increased solubility in organic solvents, improved compatibility with binder resins and enhanced resistance for nitrogen oxides. The electrophotographic photoreceptor containing the asymmetric naphthalenetetracarboxylic acid diimide compound according to the present invention can maintain a constant surface potential and durability after being repeatedly used for an extended time. The electrophotographic photoreceptor according to the present invention can provide a high image quality for an extended time. The invention is also directed to an electrophotographic imaging apparatus, an electrophotographic cartridge and to novel pyridine-substituted asymmetric naphthalenetetracarboxylic acid diimide derivatives.

    摘要： An electrophotographic photoreceptor and an electrophotographic imaging apparatus employing the photoreceptor are disclosed. The electrophotographic photoreceptor includes an electrically conductive substrate and a photosensitive layer formed on the electrically conductive substrate, wherein a latent image is formed on the photosensitive layer using a blue-violet exposure light source having a wavelength of 380 to 450 nm. The outer surface of the photosensitive layer includes a charge generating material, a charge transporting material, and a binder resin. The light transmittance of the photosensitive layer is 1.0×10−1 to 1.0×10−3 in the light exposure wavelength. The electrophotographic photoreceptor can provide high quality images with high resolution using the blue-violet exposure light source.
