There is provided an electrophotographic photoconductor comprising as a charge carrier generating substance a bisazo compound of the general formula (I):
wherein R1 and R2 are the same or different, each representing a hydrogen atom, a halogen atom, a lower alkyl group optionally substituted with a fluorine atom, an aralkyl group optionally having a substituent, a lower alkoxy group, or a di-(lower alkyl)amino group; n is an integer from 1 to 3; m is an integer from 1 to 4; and Cp1 and Cp2 are the same or different, each representing an aromatic condensed heterocyclic or aromatic condensed hydrocarbon residue having at least one phenolic hydroxyl group and optionally having a substituted carbamoyl group or a heterocyclic group.
本发明提供了一种电子照相光电导体,该光电导体包含通式(I)的双偶氮化合物作为电荷载体生成物质:
其中 R1 和 R2 相同或不同,各自代表氢原子、卤素原子、任选被氟原子取代的低级烷基、任选具有取代基的芳烷基、低级烷氧基或二(低级烷基)氨基;n 是 1 至 3 的整数;m 是 1 至 4 的整数;以及 Cp1 和 Cp2 相同或不同,各自代表芳香缩合杂环或芳香缩合烃残基,该残基具有至少一个酚羟基,并可选具有取代的氨基甲酰基或杂环基。
