ABSTRACT:
In a process for producing a chlorogallium phthalocyanine crystal comprising mechanically dry-grinding chlorogallium phthalocyanine and subjected to crystal conversion, the weight ratio of chlorogallium phthalocyanine to the grinding media is set at a range of from 1/5 to 1/1000. The resulting chlorogallium phthalocyanine crystal excels in the dispersibility in a binding resin and the stability in the dispersion.
