    Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing toner particles by which the toner particles having a small grain size and a narrow grain size distribution are generated in a shorter time and also coarse grain and soiling are eliminated. SOLUTION: This method of forming the toner particles includes a process to aggregate the toner particles by adding an aggregating agent to a latex emulsion of resin having a colorant mixed therein under a temperature condition above the glass transition temperature of the resin and a stirring condition, and a process of adding the flocculating agent consists of a first introduction to add at least about 40 wt.% of the total amount of the aggregating agent to be added at a high introduction rate and a second addition to continuously add the remaining aggregating agent at an adding rate lower than the introduction rate. When the particles grow to a desirable grain size, the particles are allowed to cool so that the temperature of the particles is lowered to the temperature below the glass transition temperature of the resin.

    Abstract: PROBLEM TO BE SOLVED: To obtain conductive polymer particles by subjecting a monomer and a conductive component to solution polymerization to give a polymer solution containing the conductive component, removing the solvent from the solution, grinding the polymer/conductive component mixture, dissolving the ground mixture in an organic phase containing a monomer, an initiator and a crosslinking agent, mixing the solution with an aqueous phase containing a stabilizer and an alkali halide, and thermally polymerizing this mixture. SOLUTION: A monomer such as methyl methacrylate in an amount of 10-30 wt.%, a conductive component such as conductive carbon black in an amount of 10-30 wt.%, and a polymerization initiator are subjected to solution polymerization in 50-80 wt.% organic solvent at a temp. of 45-120 deg.C, the polymer solution is subjected to azeotropic distillation to remove the solvent and form conductive component/polymer composite particles in aqueous phase, and the particles are dried and ground. The ground particles are added to an organic phase consisting of 50-70 wt.% monomer, 1-15 wt.% initiator and 0.01-5 wt.% crosslinking agent, which is then mixed with an aqueous phase containing a stabilizer, such as a polyvinyl alcohol, and an alkali halide. The obtained suspension is thermally polymerized to give conductive polymer composite particles having a volume-mean particle diameter of 0.05-5 μm.
