Substrate for electrophotography photosensitive body, electrophotography photosensitive body, and electrophotography device

摘要

The object of the present invention is to provide an electrophotography photosensitive body substrate, photosensitive body, and electrophotography device used in a contact charging process that can prevent the occurrence of minor insulation damage of around diameter 0.1-0.5 mm.In an electrophotography photosensitive body substrate having a sealed aluminum anodic oxidation film on its surface, the anodic oxidation film is sealed by a sealing agent in which an anion surface active agent is beneficially added.
