ABSTRACT:
A toner for developing electrostatic images is comprised of toner particles having a number average particle diameter of from 0.5 .mu.m to 5.0 .mu.m, in which toner particles with a particle diameter of 6.0 .mu.m or larger is included in a proportion of not more than 5% by number. The toner particles are obtained by a process having the steps of dispersing a monomer composition containing at least a colorant, a charge control agent, or a mixture of these, and a polymerizable monomer, in free space formed in a polymeric medium, and polymerizing the monomer composition dispersed in said free space.
