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.
