ABSTRACT:
An electrophotographic photoreceptor and an electrophotographic imaging apparatus include an asymmetric naphthalenetetracarboxylic acid diimide derivative. The asymmetric naphthalenetetracarboxylic acid diimide derivative has increased solubility in organic solvents and improved compatibility with binder resins, thus providing excellent electron transporting ability. The electrophotographic photoreceptor containing the asymmetric naphthalenetetracarboxylic acid diimide compound according to the present invention can maintain a constant surface potential 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.
