A toner produced by mixing, in a water base medium, at least a resin particle dispersion having resin particles dispersed therein, a colorant particle dispersion having colorant particles dispersed therein and a wax particle dispersion having wax particles dispersed therein together and thereafter conducting aggregation heating thereof, wherein the main component of a surfactant for use in the resin dispersion is a nonionic surfactant and further the main component of at least one surfactant selected from among the surfactant for use in the wax dispersion and the surfactant for use in the colorant dispersion is a nonionic surfactant. Thus, a toner of small particle diameter with a sharp particle size distribution can be prepared without the need to conduct classification. Further, oilless fixation can be realized, and the service life thereof can be prolonged without spending of toner components onto a carrier. Still further, image void and scattering at transfer can be avoided. Consequently, there can be provided a toner or two-component developer attaining high transfer efficiency. |
