发明名称 ELECTROPHOTOGRAPHIC SENSITIVE BODY
摘要 PURPOSE:To obtain a photosensitive body high in sensitivity and durability by raising a ratio of diffraction line intensity at the maximum peak in a specified angle range of 2theta in the powder X-ray diffraction diagram of an azo pigment to an X-ray intensity of the background to a specified value or more. CONSTITUTION:The ratio X of the diffraction line intensity at the maximum peak in the 5-20 deg. range of 2theta in the powder X-ray diffraction diagram of the azo pigment to be used as an electric charge generating material in a photosensitive layer to the X-ray intensity of the background is controlled to >=0.8, preferably >=1.0, where X is crystallization degree and X=(P-B)/B, P is the X-ray intensity at the maximum peak value, and B is the X-ray intensity at the peak position on the line allowed to join the valleys on both sides of the maximum peak. The final crystallization degree of the azo pigment in the final photosensitive layer is controlled by obtaining the interrelation between the crystallization degree in the photosensitive layer to be used in the final state and that in a liquid dispersion, thus permitting the photosensitive body high in sensitivity and durability to be obtained.
