    • PURPOSE: To impart characteristics fast and stable against heat, light, etc. and to enhance electrophotographic characteristics, such as acceptance potential, sensitivity, and residual potential, and printing resistance by using a specified trisazo compd. as a photoconductive substance for constituting the photosensitive layer of an electrophotographic sensitive body.
      CONSTITUTION: A photosensitive layer formed on a conductive substrate incorporates at least one kind of trisazo compds. represented by general formula [ I ]in which X
