ABSTRACT:
Coloring fine particles produced by heating spheroidal coloring fine particles with an average fine particle diameter of 1-100 .mu.m obtained by suspension polymerization to a temperature of 30.degree. to 200.degree. C., thereby causing the particles to fuse together in a block without completely destroying the particle interfaces, and then crushing the block to substantially the same average particle diameter of the spheroidal coloring particle before melting, and a toner for developing electrostatic images using the same.
