PURPOSE: To form images which are sharp regardless of a relatively small content of coloring agents and have particularly good transparency particularly when the coloring agents exclusive of black are used for the coloring agents by forming resin film layers by using the coloring agents and resin fine particles on the surfaces of internal nucleus particles and further to allow the easy production of the toner by uniformly and easily controlling the resin film layers regardless of the compsn. and structure of the internal nucleus particles so that the toner having multilayered structures can be produced at a low cost.

CONSTITUTION: The internal nucleus particles 5 are produced by using raw materials consisting of a binder resin 1, etc. The internal nucleus particles 5 are then subjected to an external addition treatment 6 to stick the coloring agents 2 and the resin fine particles 3, etc., thereto by which the internal nucleus particles 7 externally added with the coloring agents and the resin fine particles are produced. The internal nucleus particles 7 externally added with the coloring agents and the resin fine particles are subjected to a film forming treatment 8 by bringing a solvent 4 dissolving the resin fine particles into contact therewith to form the resin film layers 9, by which the toner 10 formed with the resin films contg. the coloring agents is produced.
