Abstract
An electrophotographic color toner containing at least a coloring agent, a binder resin, and light-color or colorless fine particles, wherein toner particles containing particles having particle sizes of at least 1.0 &mgr;m as said fine particles are not more than half of the total toner particles. The electrophotographic color toner has a broad fixable temperature region of the toner and does not cause an image deterioration by preventing the occurrence of the penetration phenomenon into a paper while keeping a high image quality and high coloring even by using paper other than a paper for color copy without deteriorating various characteristics of a toner of prior art.
