Toner, Process for Producing Toner, Two-Component Developer and Image Forming Apparatus

摘要

Toner of the present invention is produced by mixing in an aqueous medium at least a resin particle dispersion in which resin particles are dispersed, a colorant particle dispersion in which colorant particles are dispersed, and a wax particle dispersion in which wax particles are dispersed and heating and aggregating the mixed dispersion. The main component of a surface-active agent used for the resin particle dispersion is a nonionic surface-active agent. The main component of at least one surface-active agent selected from a surface-active agent used for the wax particle dispersion and a surface-active agent used for the colorant particle dispersion is a nonionic surface-active agent. With this configuration, the toner can have a smaller particle size and a sharp particle size distribution without requiring a classification process. The toner and a two-component developer can achieve oilless fixing, eliminate spent of the toner components on a carrier to make the life longer, and ensure high transfer efficiency by suppressing transfer voids or scattering during transfer.
