    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 toner is provided for forming an image on a sheet of ordinary paper using a small amount of toner which is favorable in the density, less in the difference in reflection between toner layers thereof in each color. Even when the toner is small in the consumption, its image can be high in the density and uniform in the color reproduction. The toner contains a binding resin and a coloring pigment, the coloring pigment ranging from 5 percent to 20 percent by weight, wherein the average volumetric particle diameter D is 3 to 9 μm. The calculated average surface roughness Rs of a solid image developed and fixed at 0.2 to 0.5 mg/cm2 of the adhered amount M on a transfer medium of which the calculated average surface roughness Rp is 5 to 7 μm, satisfies an relational expression Rs/Rp≦0.6×D/(10 M/ρ), where ρ is the true specific gravity of the toner in g/cm3.

    摘要： An electrophotographic toner is prepared by using a binder resin having an acid value of 5 to 15 mgKOH/g, a salicylic metal complex, a colorant, and a releasing agent. In the preparation determination for the third root distribution of a light emission voltage by helium atmospheric pressure microwave induction plasmas for carbon atoms derived from the binder resin and metal atoms derived from the salicylic metal complex is made based on a value measured by a micro-particle measuring apparatus including a normal pressure or atmospheric pressure space, a capillary tube inserted at one end in the space, a microwave source, a cavity, a quartz tubular reactor, a discharge means, an analyses means, and a signal detection portion. The absolute deviation showing the scattering of approximate straight lines approximated by a least squares method is controlled to be 0.08 or less.
