An electrophotographic toner that can be favorably colored without causing dispersibility in a thermoplastic resin as a problem, is excellent in transparency and color reproducibility, and is excellent in heat resistance, chargeability, and offset resistance. The purpose is to provide. In addition, a method for producing an electrophotographic toner that does not use a highly harmful metal and an electrophotographic toner are provided. In a method for producing an electrophotographic toner containing an oil-soluble dye in a thermoplastic resin, (1) an oil containing at least a water-insoluble organic solvent, an oil-soluble dye capable of chelating with a metal, a metal compound and water. A first step of preparing a soluble dye dispersion; (2) a second step of removing the water-insoluble organic solvent from the oil-soluble dye dispersion prepared in the first step to form colored fine particles; and (3) further A method for producing an electrophotographic toner, comprising a third step of mixing with a thermoplastic resin emulsion, slowly aggregating, and associating.
