ELECTROSTATIC LATENT IMAGE DEVELOPING TONER, ITS PRODUCTION, DEVELOPER USING SAME AND IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To improve transferability to an image support and to maintain high image quality over a long period of time. SOLUTION: At least resin particles and colorant particles are salted out and fused to obtain the objective toner. The resin particles are obtained by a polymerization method including the addition of a polymerization initiator to an aqueous medium in which a polymerizable monomer forming the resin particles has been emulsified at an average addition rate A in the range from 0.1 wt.% of the total weight of the polymerizable monomer per 1 min to 5 wt.% of the total weight of the polymerizable monomer per 1 min.
