Abstract

PURPOSE: To provide the electrophotographic sensitive body which has a high sensitivity, the high mechanical durability of an electrophotographic sensitive layer and good surface smoothness and is less degraded in image quality and sensitivity by using specific monomers as the binder of the photosensitive layer.
CONSTITUTION: The electrophotographic sensitive body which has excellent film properties and excellent electrophotographic characteristics, such as charge holding power and residual potential of sensitivity, and exhibits stable characteristics with lessened fatigue deterioration when subjected to repetitive use is formed by using a polymer contg. general formula (B1) as its main repeating unit or a copolymer contg. the general formula (B1) and general formula (B2) in its constituting compsn. as the main repeating unit. This photosensitive body exhibits an extremely improved effect in terms of sensitivity, durability and image quality, etc., if a fluorenone disazo pigment, fluorenilidene disazo pigment and polycyclic quinone are used as the carreir generating material of the photosensitive body.
