NOVELTY - The hydroxy gallium phthalocyanine has a peak in copper potassium (CuKalpha) characteristics at Bragg angle by X-ray diffraction in 7.4degrees, 9.8degrees, 12.4degrees, 12.9degrees, 16.2degrees, 18.4degrees, 23.9degrees, 25degrees, 25.9degrees and 28.1degrees. The hydroxy gallium phthalocyanine has no peak in 26.2degrees. The half value width (W) of the hydroxy gallium phthalocyanine at 25.9degrees is 0.1-0.4degrees.    USE - As photoconductor for electrophotographic sensitive component (claimed) for solar cell, sensor, switching element, optical recording, photochemical treatment of cancer and as photochemical material, deodorizing anti-microbe and catalyst.    ADVANTAGE - The hydroxy gallium phthalocyanine has a novel crystal form. The electrophotographic sensitive component using the hydroxy gallium phthalocyanine has improved sensitivity with respect to light ray of long wavelength. The variation in sensitivity is reduced and a favorable electrophotographic characteristics are obtained.    DETAILED DESCRIPTION - The hydroxy gallium phthalocyanine has a peak in copper potassium (CuKalpha) characteristics at Bragg angle (2theta+/-0.2degrees) by X-ray diffraction in 7.4degrees, 9.8degrees, 12.4degrees, 12.9degrees, 16.2degrees, 18.4degrees, 23.9degrees, 25degrees, 25.9degrees and 28.1degrees. The phthalocyanine has no peak in 26.2degrees. The half value width (W) of the phthalocyanine at 25.9degrees is 0.1-0.4degrees. INDEPENDENT CLAIMS are included for the following:    (1) Manufacture of hydroxy gallium phthalocyanine. A solvent process of hydroxy gallium phthalocyanine which has a peak in 7.4degrees, 9.8degrees, 12.4degrees, 12.9degrees, 16.2degrees, 18.4degrees, 23.9degrees, 25degrees, 25.9degrees, 26.2degrees and 28.1degrees is performed using an amido group solvent or water-amide group mixed solvent. The hydroxy gallium phthalocyanine which has no peak in 26.2degrees is obtained;    (2) Electrophotographic sensitive component comprising at least a photosensitive layer containing the hydroxy gallium phthalocyanine on a support (1);    (3) A process cartridge containing a charging component which charges the electrophotographic sensitive component, an image developing unit and a cleaning unit. The image developing unit develops an electrostatic latent image formed on the electrophotographic sensitive component using a toner. The cleaning unit collects the toner remaining in the electrophotographic sensitive component after transfer process. The process cartridge is detachable to an electrophotographic apparatus; and    (4) Electrophotographic apparatus which contains a charging unit, an exposure unit, and an image development unit and transfer unit. The exposure unit performs exposure with respect to the charged electrophotographic sensitive component to form an electrostatic latent image. The transfer unit transfers a toner image on the electrophotographic sensitive component on a transfer material.    DESCRIPTION OF DRAWING(S) - The figure shows the outline composition of the electrophotographic sensitive component.    Support (1)    Charge generating layer (4)    Electric charge carrying layer (5)
