PROBLEM TO BE SOLVED: To provide a management method for a coating liquid for an electrophotographic photoreceptor by which the dispersed state of the coating liquid can stably be maintained over a prolonged period of time in order to manufacture single layer type photoreceptors at a low cost. SOLUTION: In the management method for a coating liquid for an electrophotographic photoreceptor, the coating liquid for a photosensitive layer prepared by dispersing or dissolving at leastα-titanyl phthalocyanine, a hole transport material, an electron transport material and a polycarbonate resin in tetrahydrofuran is stored at an environmental temperature of≤15°C. The coating liquid for a photosensitive layer is preferably a liquid prepared by mixing a solution A prepared by dispersingα-titanyl phthalocyanine particles in a solution of a polycarbonate resin in a tetrahydrofuran-based solvent and a solution B prepared by dissolving a hole transport material, an electron transport material and a polycarbonate resin in tetrahydrofuran.
