A method for producing electrophoretic particles includes dispersing
particles having a charge on the surfaces thereof in an polar dispersion
medium; adding a first polymerizable surfactant including a first polar
group having a polarity opposite to the charge of the surfaces of the
particles, a hydrophobic group, and a polymerizable group to the polar
dispersion medium and mixing the liquid; adding a second polymerizable
surfactant including a second polar group, a hydrophobic group, and a
polymerizable group to the polar dispersion medium and emulsifying the
mixture; and adding a polymerization initiator to induce polymerization
reaction, thereby preparing electrophoretic particles in which the
particles are coated with an organic polymer. In the method, the charge
polarity and the amount of charge of the electrophoretic particles are
controlled by setting the polarity of the second polar group included in
the second polymerizable surfactant, and at least one condition of the
number of the second polar groups in second polymerizable surfactant, the
valence of the second polymerizable surfactant, and the molar amount of
the second polymerizable surfactant added.
