摘要： A two-component developer and an image formation method for two-component development type are provided. With this developer and this method, even if toners have a small grain diameter and a high density of pigments for economizing the toner consumption, cracking and toner spent caused by the stress from carriers are suppressed, so that less deteriorated and stabler images can be obtained throughout a long time period. The two-component developer includes toner particles containing at least a binding resin and a pigment. A mean volume particle diameter of the toner particles is between 5.5 μm and 7 μm. A number percent of the toner particles with a mean volume particle diameter of 5 μm or below, and a volume percent of the toner particles with a mean volume particle diameter between 8 μm and 12.7 μm, with respect to the total toner particles, respectively, are set to be within a predetermined range. Density of the pigment in the toner particles is between 8 weight percent and 20 weight percent. The two-component developer also includes carrier particles which are resin-coated carrier particles. A mean volume particle diameter of the carrier particles is between 35 μm and 65 μm. The two-component developer allows the formation of less deteriorated and stabler images throughout a long time period.

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.
