PROBLEM TO BE SOLVED: To provide resin particles having a uniform particle diameter and having only a small amount of an inorganic dispersant such as silica adhered to a surface thereof.SOLUTION: Provided are resin particles having an inorganic dispersant adhered on a surface thereof, whose volume average particle size is 1 to 1000 μm. An coating amount of the inorganic dispersant on the resin particle surface is 0.0001 to 0.02 g/m, the coating amount being determined by the following formula (I): Coating amount of inorganic dispersant on resin particle surface=(amount of inorganic dispersant (pts.wt)/amount of polymerizable monomer (pts.wt))/specific surface area of resin particle as measured by Mastersizer 2000 manufactured by Malvern Instruments Ltd. (where, the amounts of the inorganic dispersant and the polymerizable monomer in the right side of the formula (I) are charge amounts at the time of production, and the amount of the polymerizable monomer is set to 100 pts.wt.). |
