摘要： A method for manufacturing a toner includes a pre-mixing step and a coating step. In the pre-mixing step, a secondary aggregate of the fine resin particles is disaggregated, while toner base particles and fine resin particles are mixed and stirred using a rotary stirring apparatus. Thus obtained disaggregated fine resin particles are fixed to the surface of the toner base particle. Thus, a fine resin particle-fixed toner is obtained. The rotary stirring apparatus includes a rotary stirring section, a temperature regulation section, a circulating section, and a spraying section. In the coating step, a liquid is sprayed to the fine resin particle-fixed toner with the spraying section using the rotary stirring apparatus. Thus, a film of the fine resin particles is formed. In the pre-mixing step and the coating step, temperature regulation is conducted in the temperature regulation section.

摘要： A method for manufacturing a developing agent comprising dissolving a binder resin component in a supercritical fluid or a subcritical fluid, mixing it with a colorant component, reducing the solubility of the binder resin component in the supercritical fluid or subcritical fluid, and causing the binder resin component to be deposited in the form of particles while the colorant component is dispersed within the binder resin component. After the pressure within a reaction vessel is decreased from A (MPa) to B (MPa) (where A>B>critical pressure) following the manufacture of a developing agent, the method proceeds back to a developing agent manufacturing step again when at least a developing agent material and a supercritical fluid or a subcritical fluid are injected into the reaction vessel under high pressure. The method allows the dispersibility of the colorant component in the developing agent to be increased up to a primary particle level, whereby a developing agent with an even particle shape and a narrow particle size distribution can be obtained. The method also makes continuous production possible without the need to open and close the reaction vessel, leading to a high production efficiency.

摘要： A manufacturing apparatus provided with a rotary stirring section and a powder passage is used to manufacture the resin-layer coated carrier. At a fine resin particle adhering step, a magnetic base particle and a fine resin particle are inputted into the powder passage with the rotary stirring section rotating and the fine resin particle is adhered onto the surface of the magnetic base particle. At a spraying step, at least a liquid that plasticizes the fine resin particles is sprayed with spray gas from a spraying section on the magnetic base particle and the fine resin particle which are in a fluidized state in the powder passage. At a film-forming step, rotation by the rotary stirring section is continued to fluidize the magnetic base particles and the fine resin particles until the fine resin particles adhered to the magnetic base particles are softened to form a film.
