ABSTRACT:
An electrophotographic photoreceptor comprising a conductive substrate having provided thereon a photoconductive layer is disclosed, said photoconductive layer containing a high polymeric compound comprising a repeating unit comprised of a tetracarboxylic acid anhydride skeleton and a divalent organic group skeleton having an aromatic nucleus, said two skeletons being bonded via a nitrogen atom. Said high polymeric compound is formed by co-deposition of a tetracarboxylic acid anhydride compound and an aromatic diamine compound. The photoreceptor exhibits high sensitivity, high durability, and excellent image quality retention even when used repeatedly or in a high humidity environment.
