PURPOSE:To eliminate an induction effect and to improve the sensitivity of the titled sensitive body using photoconductive phthalocyanine powder in the visible light region by incorporating a specified disazo pigment and a specified pyrazoline compound into the photosensitive layer. CONSTITUTION:A disazo pigment represented by formula I (where X is -OCH3 or Cl) such as Dian blue and a pyrazoline compound represented by formula II[where (n) is 0 or 1, and each of A, A1 and A2 is aryl] such as 1-phenyl-3-(p- dimethylaminostyryl)-5-(p-dimethylaminophenyl)-pyrazoline are used as sensitizers. A photoconductive coating material is prepd. by kneading photoconductive phthalocyanine powder with said disazo pigment, said pyrazoline compound and a binder resin, and the coating material is applied to an electrically conductive support to form a photosensitive layer of about 2-20mum thickness. Thus, a single layer type electrophotographic sensitive body is obtd. |
