To supply color toners capable of achieving satisfactory image density and color reproducibility independently of a printing surface in image formation, capable of forming a uniform high density image comparable to that by planographic printing and capable of forming a clear image with small amount of the toner.

A high density clear image is obtained with small amount of toner by controlling the thickness of a toner image after fixation formed on a printing medium and appropriately designing the concentrations of pigment in the toner and the melting characteristics of the toner.
