Abstract
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 ML,/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,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),prepared by a wet method and a silane compound is preferably used.
