Claims
- 1. Resin particles substantially spherical in shape having a weight average particle size of 1 to 30 microns and containing 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 being prepared by polymerizing a polymerizable monomer in an organic solvent having a higher solubility parameter 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; wherein said resin particles have said dispersion stabilizer on the surface of said resin particles.
- 2. The particles according to claim 1 wherein said dispersion stabilizer contains 1 to 35% by weight of a silicon atom and is present in an amount of 1 to 20% by weight based on an amount of the polymerizable monomer.
- 3. The particles according to claim 1, wherein said dispersion stabilizer contains 1.times.10.sup.-1 to 20% by weight of a fluorine atom and is present in an amount of 1 to 20% by weight based on an amount of the polymerizable monomer.
- 4. The particles according to claim 1 wherein the polymerization reaction is conducted in the presence of a coloring agent.
