摘要:
A process for producing a toner comprising:heating a monomer composition containing at least a polymerizable monomer and a release agent to a temperature not lower than the melting point or the softening point of said release agent todissolve the release agent in the polymerizable monomer and therebypreparing a monomer composition in which the release agent is dissolved;cooling the monomer composition to a temperature lower than the melting point or the softening point of the release agent to precipitate said release agent and therebypreparing a monomer composition containing the precipitated releasing agent particles having a number average size of 0.5 to 5 .mu.m;granulating in an aqueous dispersion medium the monomer composition to prepare a particle;carrying out suspension polymerization of the particle of the monomer composition at a temperature lower than the melting point or the softening point of the release agent.
