Abstract
PURPOSE: To impart high sensitivity and high flexibility to a photoreceptor, by providing a photosensitive layer containing a specified disazo pigment as an effective constituent on a conductive substrate.
CONSTITUTION: To a charge transferring substance of a photosensitive layer formed on a conductive substrate is added a disazo pigment having a distyrylbenzene skeleton represented by the general formula in which Ar is phenyl, naphthyl, pyrenyl, carbazolyl, or the like. This disazo pigment is effective for an electrophotographic process, and easily obtained by coupling e.g. 1,4-distyrylbenzene-4,4'- bisdiazoniumtetrafluoroborate with a corresponding coupler in a proper solvent in the presence of an alkali.
