Estimating the term…
A full-color latent image developing toner composed of toner particles containing a binder resin, a coloring agent, and a surface lubricant, and at least one kind of an external additive, wherein the toner contains at least about 3% the surface lubricant, the toner includes irregular-shaped particles of ML2/A≧125, and when the emission voltage caused by the carbon originated in the binder resin of the toner particles is X and the emission voltage caused by the element originated in the external additive is Y, and when the relationship between X(⅔) and Y are primary-regressed to the straight line passing through origin of a coordinate, the correlation factor of the element originated in at least one external additive is not less than 0.4. As the external additive, a titanium compound obtained by reacting TiO(OH)2 prepared by a wet method and a silane compound is preferably used.
A full-color electrostatic latent image developing toner comprising a toner particles containing a binder resin, a colorant, and a release agent, and at least one kind of an external additive, wherein the amount of the release agent is at least about 3%, the toner particles having irregular-shaped toner of ML2/A≧125, and when an emission voltage caused by the carbon originated in the binder resin of the toner particles is X and an emission voltage caused by the element originated in the external additive is Y, and when the relationship of X(⅔) and Y are primary-regressed to an straight line passing through origin of a coordinate, the correlation factor of the element originated in at least one kind of the external additive is not less than 0.4.
