ABSTRACT:
Disclosed is a process for preparing polymer particles suitable for electrophotographic toner. The substantially spherical resin particles have a weight average particle size of 1 to 30 microns and contain a carbon atom as main component, a silicon atom in an amount of 1.times.10.sup.-1 to 7% by weight and/or a fluorine atom in an amount of 1.times.10.sup.-2 to 2% by weight. The particles are prepared by polymerizing a polymerizable monomer in an organic solvent having a higher solubility parameter (SP value) than the resultant polymer by at least 1.0 in the presence of a dispersion stabilizer which is soluble in said organic solvent and which has a dialkylsiloxane bond and/or a fluorine atom, and then removing said organic solvent.
