The dispersion effect in solution making a positively charged monolayer photoreceptor consisting of x-type metal-free phthalocyanine (x-H2Pc) and a binder resin is studied. The photoreceptor is characterized by a high photosensitivity due to a new specific interaction between x-H2Pc and the binder resin.1 It is suggested that the characteristics of the solution structure and the chemical actions significantly affect the behavior of x-H2Pc. To clarify more this behavior, the solution state is examined by viscometry, and the solid state is examined by X-ray diffraction, transmission and scanning electron microscope, and ion potential and xerographic measurements. From these results, it was found that the dispersion process of the x-H2Pc pigment, depending on the composition and the dispersion time of the solution, significantly influences the physical properties and the electrophotographic characteristics of the monolayer photoreceptor.
