Abstract: The present invention uses an azo pigment having in the center of an N-oxide heterocyclic structure as a photoelectrical charge-generating material. The pigments are excellent in dispersion stability in a dispersed solution, and enable the provision of a photosensitive member excellent in sensitivity properties.
