An object of the present invention is to provide a toner having remarkably improved developability such as development streaks and fog, image friction and fixability such as image peeling. SOLUTION: At least a polymer fine particle, a colorant fine particle, a crystalline polyester fine particle, and a wax fine particle are aggregated to form a fine particle aggregate, and an aging step for causing fusion between the fine particles in the fine particle aggregate. In the emulsion aggregation method toner obtained through The crystalline polyester has a weight average molecular weight Mw of 1000 or more and 5000 or less, The wax component is a wax having a melting point of 45 to 75 ° C. The toner is characterized in that the methanol concentration (volume%) at a transmittance of 50% in methanol wettability is 30 to 70%. [Selection figure] None |
