COATING LIQUID FOR ELECTROPHOTOGRAPHIC PHOTOSENSITIVE BODY, ELECTROPHOTOGRAPHIC PHOTOSENSITIVE BODY, AND ELECTROPHOTOGRAPHIC PHOTOSENSITIVE BODY CARTRIDGE

摘要

Disclosed is a coating liquid for producing an electrophotographic photosensitive body, which is excellent in electrical characteristics and mechanical durability, while being excellent in coatability and liquid stability. Also disclosed are an electrophotographic photosensitive body produced by using such a coating liquid, an image-forming device comprising such an electrophotographic photosensitive body, and an electrophotographic photosensitive body cartridge. Specifically disclosed is a coating liquid for producing an electrophotographic photosensitive body, which is characterized by containing a copolymerized polycarbonate resin and asolvent A having a boiling point of not less than 80°C but not more than 150°C. The copolymerized polycarbonate resin has a repeating unit represented by the formula (1) below, while containing not more than 10% by weight of a repeating unit having a biphenyl structure. The average of repetitions of the unit represented by the formula (1) is not more than 10.
