    摘要： An electrophotographic photoreceptor includes an electron transporting material in a charge-generating layer. The electrophotographic photoreceptor includes a conductive substrate; a charge generating layer formed on the conductive substrate and includes a charge generating material and electron transporting material; and a charge transporting layer formed on the charge generating layer and includes a charge transporting material, wherein the electron transporting material is a phenylazomethylene-cyclohexadienone derivative represented by the following Formula I: wherein R1 and R2 are independently selected from the group consisting of a substituted or unsubstituted C1-C20 alkyl, substituted or unsubstituted C1-C20 alkoxy, substituted or unsubstituted C6-C30 aryl, substituted or unsubstituted C7-C30 aralkyl and a halogen; A is selected from the group consisting of nitro, cyano and sulfone; 1 is an integer between 1 and 4; m is 0 or an integer between 1 and 4; and n is an integer between 1 and 5. The electrophotographic photoreceptor shows high sensitivity and low exposure potential.

    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.
