A process for producing electrophoretic particles containing core particles includes a step of forming the core particles by polymerization of a composition comprising a colorant, a first polymerizable monomer, a second polymerizable monomer having a functional group which is capable of reacting with a living radical polymerization initiation group precursor, and a polymerization initiator; a step of providing a living radical polymerization initiation group at a surface of each core particle by reacting a compound having the living radical polymerization initiation group precursor with the functional group; and a step of providing a polymer chain to the living radical polymerization initiation group by living radical polymerization.
