Preferably, the amount of the component A to be used is 0.1-10wt.% based on the water-soluble ethylenic unsaturated monomer, whereas for the component B, 0.05-5wt.%.

In the formulas, R1 denotes a alkyl of 1-18C, H; R2 denotes H, CH3; A denotes alkylene of 2-4C; l denotes 1-20; m denotes 1-5; n denotes 1-100. The charge control agent is preferably an azo metallic complex dye (e.g. the dye expressed by the formula III). This toner is obtd. by dispersing the charge control agent, coloring agent, etc., in the presence of the above- mentioned deriv. into a polymerizable monomer, then subjecting the dispersion to a suspension polymn.
