ELECTROPHOTOGRAPHIC PHOTORECEPTOR |
摘要 |
PROBLEM TO BE SOLVED: To provide an organic electrophotographic photoreceptor more excellent in durability than a conventional one because it has an inorganic surface protecting layer less liable to cause a cracking and peeling in a practical service environment and due to a long-term storage and excellent in physical stability. SOLUTION: The electrophotographic photoreceptor is obtained by stacking an organic photosensitive layer and an inorganic surface protecting layer in this order, and the top part of the organic photosensitive layer brought into contact with the surface protecting layer contains a dinaphthoquinone derivative of formula (1) [where R1-R4 are mutually the same or different and each H, an alkyl, alkoxy, aryl or an aralkyl].
