Abstract: Toner for electrostatic development in accordance with one aspect of the present invention contains toner base particles produced by subjecting a toner composition containing binder resin, a coloring agent, and wax to melting and kneading and thereafter pulverization and classification, the toner having a volume median particle diameter (D50) of 5.5 to 7.5 ?m, and the toner having particle size distribution in which the toner base particles include 15 to 55% by number of toner base particles of not more than 5 ?m in particle diameter, and include not more than 1.5% by number of toner particles of more than 10 ?m in particle diameter.

Abstract: An electrostatic-image-developing toner includes a binder resin that contains a crystalline polyester resin and an amorphous polyester resin; and a coloring agent, wherein the crystalline polyester resin has a melting temperature Tmc of about 25° C. or greater but not greater than about 50° C., and a content of the crystalline polyester resin in the electrostatic-image-developing toner is about 3 wt % or greater but not greater than about 15 wt. %.

Abstract: An electrophotographic image forming method is disclosed, which includes the steps of developing an electrostatic image on a electrophotographic photoreceptor by a developer, transferring a toner image formed by the development, and fixing the toner image on a recording medium. It is disclosed that a toner has a volume particle diameter (Dv50) of about 4.4 to about 5.8 ?m and displays two or more endothermic peaks measured by DSC being within the rang of from about 50 to about 73° C. and the endothermic heat amount thereof is from 12.6 to 24.5 J/mg and a transferring member and/or a fixing member constituted by a belt containing a polyimide resin are employed in the method.

Abstract: An electrophotographic image forming method is disclosed. The method contains steps of forming an electrostatic latent image on an organic photoreceptor, and developing the electrostatic latent image by a developer containing toner to form a toner image on the photoreceptor. In this method the photoreceptor contains inorganic particles in a surface layer, the toner has circle equivalent diameter d of 3.0 to 8.0 ?m viewed from a direction which maximizes the projective area of toner particles, the toner has a flatness ratio d/t of 2.0 to 5.0, wherein d is circle equivalent diameter and t is average thickness of toner particles, and the electrostatic latent image is developed in such a manner that the developing sleeve is rotated in the opposite direction to the photoreceptor.

Abstract: A toner includes toner particles containing at least a binder resin and a colorant, and inorganic fine particles. The shape factor SF-1 of the toner particles is in a specific range. The toner has a storage elastic modulus at 140° C., G? (140° C.), in a specific range the toner comes to have a viscosity of 1.0×103 Pa·s according to a flow tester heating method at a temperature of from 115° C. or more to less than 130° C.
