    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.
