摘要： The present invention is a carrier for electrophotography in which a surface of at least a core material is coated with a resin, in which the coating resin contains a fluorine modified silicone resin and an aminosilane coupling agent, and in which the carrier charges a toner negatively. Consequently, a carrier with a high durability and a long lifetime for electrophotography is provided, in which the charge amount does not decrease at high temperature or high humidity nor extremely increase at low temperature or low humidity, in which a deterioration of a developing agent caused by stripping of a coating layer is prevented, and in which a deterioration caused by formation of spent toner of a toner is not caused.

摘要： Toner includes aggregated and associated particles formed by mixing in an aqueous medium at least a resin particle dispersion in which resin particles are dispersed, a colorant particle dispersion in which colorant particles are dispersed, and a wax particle dispersion in which wax particles are dispersed and heat-treating the mixed dispersion for aggregation. The aggregated and associated particles include first particles having a capsule structure in which aggregated wax with an average particle size of greater than 1 μm is incorporated into the resin, and second particles formed of the resin and the wax in a mixed and dispersed state. The toner can achieve oilless fixing that prevents offset without using oil while maintaining high OHP transmittance and also can eliminate spent of the toner components on a carrier to make the life longer.

摘要： A toner of the present invention includes a first wax and a second wax. The endothermic peak temperature of the first wax by the DSC method is 50° C. to 90° C. The endothermic peak temperature of the second wax is 5° C. to 50° C. higher than that of the first wax. Jmw1/Jw1 is 0.5 or less and Jmw2/Jw2 is 0.5 to 1.2, where Jw1 represents the endotherm of the first wax, Jw2 represents the endotherm of the second wax, Jmw1 represents the melting endotherm of the first wax by the MDSC method, and Jmw2 represents the melting endotherm of the second wax. The first wax and the second wax are mixed into a dispersion beforehand, the dispersion is then mixed with a resin particle dispersion and a colorant particle dispersion, and the particles are aggregated to form core particles. Thus, a toner having a small particle size and a sharp particle size distribution can be produced without requiring a classification process.

摘要： A toner of the present invention is a toner comprising an additive and a toner matrix that contains a binder resin, a colorant, and a wax, in which the additive contains an inorganic micropowder to whose surface polysiloxane and at least one selected from fatty acids and derivatives thereof are adhered. Thus, the present invention provides the toner, a two-component developer, and an image forming method with which oil-less fixing is possible without the use of an oil on a fixing roller. Furthermore, the present invention provides the two-component developer that causes less carrier deterioration by toner-spent even when used in combination with a toner containing wax or another such release agent and thus the developer has good durability. In addition, the present invention provides the toner, the two-component developer, and the image forming method with which partial transfer defects are reduced and high transfer efficiency can be obtained.

摘要： First toner of the present invention includes colored particles and an external additive. The colored particles are produced by heating and aggregating a mixture that includes a resin particle dispersion in which first resin particles are dispersed and a pigment particle dispersion in which pigment particles are dispersed, so that at least part of the first resin particles is melted. The colored particles have a finely roughened surface. Second toner of the present invention includes aggregated particles including at least first resin particles and pigment particles, and colored particles having a finely roughed surface formed by fusing at least part of wax and at least part of second resin particles on the surface of the aggregated particles. Third toner of the present invention includes aggregated particles including at least first resin particles and pigment particles, and colored particles having a finely roughened surface formed by fusing at least part of third resin particles and at least part of fourth resin particles on the surface of the aggregated particles. When the aggregated particles are formed in an aqueous medium, the pH is controlled in the specified range. The toner can achieve oilless fixing that prevents offset without using oil while maintaining high OHP transmittance. Therefore, it is possible to eliminate the spent of toner components on a carrier and to make the life longer. Moreover, thinning or scattering during transfer can be suppressed, thus ensuring high transfer efficiency.
