含有萘四甲酸二酰亚胺衍生物的电子照相感光体作为电荷产生层中的电子传输材料和使用感光体的电子摄影成像装置

Electrophotographic photoreceptor containing naphthalenetetracarboxylic acid diimide derivatives as electron transport materials in charge generating layer and the electrophotographic imaging apparatus using the photoreceptor
Abstract:
A two-layered electrophotographic photoreceptor is formed. The two-layered electrophotographic photoreceptor includes an electrically conductive substrate and a charge generating layer and a charge transporting layer form on the electrically conductive substrate, wherein the charge generating layer is a naphthalenetetracarboxylic acid diimide derivative represented by: The two-layered electrophotographic photoreceptor has high photosensitivity and low residual potential.
