1. Resin beads being resin particles, each having a roughened surface,
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 a non-polymerizable silicone compound, and
the non-polymerizable silicone compound is at least one material selected from the group consisting of silicone-acrylic copolymers, polyether-modified silicones, polyether-alkyl-modified silicones, and silicone elastomers.
