Process for producing toner for developing electrostatic images |
摘要 |
A toner for developing electrostatic latent images is produced by a process comprising the steps of: (a) preliminarily dispersing a monomer composition comprising at least a polymerizable monomer and a colorant in a liquid dispersion medium which is substantially mutually-insoluble with the monomer and contains a fine powdery dispersion stabilizer, thereby to form a liquid dispersion containing the preliminarily dispersed monomer composition; (b) pressurizing the liquid dispersion up to a pressure of 10 kg/cm2 or above; (c) ejecting the dispersion into a low pressure section to form particles of the monomer composition; and (d) subjecting the particles of the monomer composition to suspension polymerization, thereby to produce toner particles.
