PURPOSE: To provide a full color toner having stable color reproducibility, high image density, and high durability.

CONSTITUTION: In a full color toner in which at least one or more of yellow toner, magenta toner and cyan toner (referred to as colored toners) is properly selected and used together with black toner to form a color image, the colored toners are nonmagnetic toners in which an external additive is added to colored resin particles in which a coloring agent is mixed and dispersed in a binding resin, and the black toner is a magnetic toner in which the external additive is added to magnetic resin particles in which a black magnetic powder having a FeO content in magnetic iron oxide ranging from 25 to 30wt.% and a releasing agent are mixed and dispersed in a binding resin. The binding resin used in the colored toner has at least one peak in the area of molecular weights of 1,000-100,000, and the binding resin used in the black toner has at least one peak or shoulder in the area of molecular weights of 15,000-100,000.
