Abstract
A photoconductor for electrophotography, includes a conductive substrate; a photosensitive layer containing charge generation material formed on the conductive substrate. The charge generation material contains a substituted or unsubstituted gallium phthalocyanine dimer (GaPhC dimmer) and a substituted or unsubstituted hydroxy gallium phthalocyanine (GaPhC monomer) and has distinctive diffraction peaks at the Bragg angles (2θ±0.2) of 7.5° and 28.3° in a Cu-Kα characteristic X-ray diffraction spectrum.

A photoconductor for electrophotography, comprising:
- a conductive substrate;
- a photosensitive layer containing a charge generation material, the photosensitive layer formed on the conductive substrate,
- wherein the charge generation material contains a mixed compound of a substituted or unsubstituted μ-oxo-gallium phthalocyanine dimer and a substituted or unsubstituted hydroxy gallium phthalocyanine and the mixed compound has distinctive diffraction peaks at the Bragg angles (2θ±0.2) of 7.5° and 28.3° in a Cu-Kα characteristic X-ray diffraction spectrum, wherein the charge generation material contains the substituted or unsubstituted μ-oxo-gallium phthalocyanine dimer and the substituted or unsubstituted hydroxy gallium phthalocyanine in a ratio of 30-98/70-2 based on mol-ratio.
