摘要： A toner in form of aggregate of resin-containing particles is manufactured by aggregating the resin-containing particles which contain binder resin and the colorant, with the aid of an aggregate dispersant containing a polymer in which anionic polar groups are bonded to a main chain. To be specific, salt of divalent or higher valent metal is added to a slurry of the resin-containing particles so that a metal ion and the anionic polar group are bonded to each other, and a temperature of the slurry is increased so that a bond between the anionic polar group and a water molecule is broken. This decreases water-solubility of the polymer so that the resin-containing particles are aggregated.

摘要： Resin particles containing at least binding resin and wax particles having a diameter of 30 to 600 nm are coagulated, and a resulting coagulated product is heated. Such wax particles are manufactured, for example, by way of a coarse particle preparing step, a slurry preparing step, a pulverizing step, a cooling step, and a depressurizing step. Slurry of wax coarse particles obtained by way of the coarse particle preparing step and the slurry preparing step is directed under heat and pressure through a pressure-resistant nozzle whereby the wax coarse particles are pulverized into the wax particles at the pulverizing step. The cooling step and the depressurizing step are disposed just after the pulverizing step to prevent the wax particles from coarsening.

摘要： According to the method of producing toner, toner is produced by (i) forming particles of a pigmented resin by applying shear stress to a mixture of a pigmented resin composition, an organic solvent, a polymer dispersing agent, and a hydrophobic medium, the organic solvent being capable of reducing viscosity of the pigmented resin composition, and said polymer dispersing agent having a glass transition point in a range of 50° C. to 80° C. and an SP value in a range of 8.5 to 10, (ii) distilling off the organic solvent, and (iii) separating the toner from the hydrophobic medium and drying the toner. With the above arrangement, the method makes it possible to (i) easily downsize toner particle without causing thermal decomposition of a resin or separation of a release agent, and (ii) produce toner that is small in particle size, excellent in humidity-resistance, and less likely to aggregate.

摘要： A toner is manufactured by way of a coarse particle preparing step, a slurry preparing step, a pulverizing step, a cooling step, and a depressurizing step. Slurry of toner coarse particles obtained by way of the coarse particle preparing step and the slurry preparing step is made to pass under heat and pressure through a pressure-resistant nozzle whereby toner coarse particles are pulverized into diameter-reduced toner particles. By providing the cooling step immediately after the pulverizing step, dispersion of wax component into the toner particles is promoted. And by further providing the depressurizing step, bubbling and coarsening of the toner particles due to the bubbling are prevented. By so doing, there is obtained a diameter-reduced toner particle in which wax is evenly dispersed and which does not cause bleeding out.
