发明名称 TONER, METHOD OF MANUFACTURING TONER, DEVELOPER, DEVELOPING DEVICE, AND IMAGE FORMING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide toner capable of forming a high-definitionimage of high quality, by fully restraining the toner from being splashed, and by restraining new toner particles from being generated in a developing device, and to provide a method of manufacturing the toner, a developer, the developing device, and an image forming device provided therewith. Ž<P>SOLUTION: This toner contains a plurality of toner particles, containing a binder resin and a coloring agent, a content of small size particles of the toner particles having 0.5 μm-2.0 μm of circle-equivalent diameter is 5 number% or less with respect to total toner particles, in measurement by a flow particle image analyzer; a content of medium size particles C of the toner particles having a circle-equivalent diameter more than 2.0 μm and 4.0 μm or less is 20 number% or more to 30 number% or less with respect to total toner particles; a content of large size particles D of the toner particles having a circle-equivalent diameter of more than 4.0 μm and 6.0 μm or less is 50 number% or more to 70 number% or less with respect to total toner particles; and a shape factor SF1 of the toner particle is 130 or more to 140 or less.
