PROBLEM TO BE SOLVED: To produce a hydroxygallium phthalocyanine for achieving high image quality and high stability of an electrophotographic apparatus (an image-forming apparatus such as a copying machine and a laser printer). SOLUTION: The method for producing a hydroxygallium phthalocyanine comprises hydrolyzing a gallium phthalocyanine compound represented by formula (I) (wherein X is an alkyl group which may have a substituent, an alkenyl group which may have a substituent, alkynyl group which may have a substituent, an aralkyl group which may have a substituent, a cycloalkyl group which may have a substituent, an aryl group which may have a substituent or hydrogen and the substituent includes an alkoxy group, an alkylthio group, an alkyl group, a halogen atom, a nitro group, an amino group, an aryl group, a carboxy group, and a cyano group; R1 to R16 are each hydrogen, an alkoxy group, an alkylthio group, an alkyl group, a halogen atom, a nitro group or an aryl group; and n is an integer of 1-3).
