    摘要： A process for the preparation of toner generated by mixing (1) a colorant dispersion containing a preferably nonionic surfactant, and (2) a latex emulsion, and wherein the latex emulsion preferably contains resin or polymer and a surfactant, and wherein the colorant nonionic surfactant is of the Formulas (I) or (II), or optionally mixtures thereof
    wherein R 1 is a hydrophobic aliphatic, or hydrophobic aromatic group; R 2 is selected from the group consisting of hydrogen, alkyl, aryl; R 3 is hydrogen or alkyl; A is a hydrophilic polymer chain, and m represents the number of A segments.
