Coloring fine particles and toner for developing electrostatic images using the same

摘要

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 DEG to 200 DEG 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 particles before melting, and a toner for developing electrostatic images using the same.
