<p>It is an object of the present invention to obtain resin particles having a small amount of an inorganic dispersing agent (such as silica) adhering to their surfaces and having uniform particle diameters. [Solution to problem] The resin particles of the present invention are resin particles having an inorganic dispersing agent adhering to their surfaces and having a volume mean particle diameter of ito 1000 pm, and are characterized in that the amount of the inorganic dispersing agent adhering to the resin particle surfaces is in the range of 0.0001 to 0.02 g/m2, said amount being determined by the following equation (I) Amount of inorganic dispersing agent adhering to resin particle surfaces = (amount of inorganic dispersing agent(part(s) by weight) /amount of polymerizable monomer (part(s) by weight))/resin particle specific surface area as measured by (I) (wherein the amount of the inorganic dispersing agent and the amount of the polymerizable monomer in the right-hand member of the equation (I)are each an amount introduced in the production of resin particles,and the amount of the polymerizable monomer is 100 parts by weight).</p> |
