1. Resin beads being resin particles comprising a non-polymerizable silicone in a fixed state,
wherein the resin particles are a product of suspension polymerization of a monomer mixture comprising a plurality of monomers each having a copolymerizable functional group, in the presence of at least the non-polymerizable silicone,
the non-polymerizable silicone is at least one material selected from the group consisting of silicone-acrylic copolymers, polyether-modified silicones, polyether alkyl-modified silicones, trimethylsiloxysilicates, and silicone elastomers, and
at least 20% by mass of the monomer having a copolymerizable functional group in the monomer mixture is a monomer having a plurality of copolymerizable functional groups.
