摘要： An electrophotographic photoconductor that stabilizes electrical performances and prevents generation of image faults such as memories, irrespective of types of organic materials of resin binder and charge transport material, and variation of temperature and humidity of the operation environment. An electrophotographic photoconductor includes at least a photosensitive layer formed over a conductive substrate, wherein the photosensitive layer contains a cyclohexane dimethanol-diaryl ester compound represented by the formula (I): in formula (I), each of R1 through R10 represents independently, a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group of carbon number of from 1 to 5, a substituted or unsubstituted aryl group, or a substituted or unsubstituted alkoxy group of carbon number of from 1 to 5.

摘要： An electrophotographic photoconductor includes an undercoat layer and a photosensitive layer sequentially provided on a conductive substrate. The undercoat layer is mainly composed of a resin and contains a metal oxide. The resin is provided by mixing and polymerizing raw materials of aromatic dicarboxylic acid in a range of 0.1 to 10 mol %, two or more types of dicarboxylic acid other than the aromatic dicarboxylic acid, two or more types of diamine, and at least one type of cyclic amide compound. The resin exhibits an acid value and a base value each of at most 6.0 KOH mg/g. Advantageously, generation of secondary aggregates in the undercoat layer, which result in image defects such as black spots and fogging on a white field, is suppressed.
