Abstract:
1. A coating composition for an electrophotographic photoreceptor that forms a charge-generating layer by being ejected from ejection nozzles in a form of droplets, the coating composition comprising: a charge-generating substance, a binding resin, and a solvent, a viscosity of the coating composition being in a range of 1 mPa·s to 10 mPa·s, wherein the solvent contains two high-boiling point solvents having a boiling point of 150° C. to 260° C. and a low-boiling point solvent having a boiling point of at least 30° C. and less than 120° C., a difference in a boiling point between the two high-boiling point solvents is in a range of 70° C. to 110° C., a difference in a boiling point between the low-boiling point solvent and the two high-boiling point solvents is 70° C. or more, and wherein the two high-boiling point solvents are contained at a ratio of 5 parts by weight to 40 parts by weight with respect to 100 parts by weight of the coating composition for an electrophotographic photoreceptor.
