摘要

Those disclosed herein is a process for producing oxytitanium phthalocyanine as a charge generating material. The method 100 oxytitanium phthalocyanine raw material and sulfuric acid 30 to 100% by weight: wet mill filled with glass beads or zirconia as grinding media, mixing in a mixing ratio of 1, the mixture: 1 to 1 in, at -20~60 ℃, grinding process homogeneously from 0.1 to 24 hours; From the mixture is ground, the grinding media and, including the step of removing it using a solvent. According to the method, it is possible reactants difficult to handle and expensive, for example, available oxytitanium phthalocyanine, to produce without the use of pentafluoropropionic acid and trifluoroacetic acid as a high quality charge generating material.
