PROBLEM TO BE SOLVED: To provide a method of producing electrophoretic particles with which the electrophoretic particles with a desired charged state are easily produced, an electrophoretic dispersion containing the electrophoretic particles produced with the method, microcapsules having the electrophoretic dispersion with high reliability, an electrophoretic display device and an electronic apparatus. SOLUTION: The method for producing the electrophoretic particles 5 includes: dispersing particles 50 having a charge in an aqueous dispersion 90; adding a first polymerizable surfactant 61 including a polar group 611 having a polarity opposite to the charge of the particles to the aqueous dispersion 90; adding a second polymerizable surfactant 62 including a polar group 621 thereto and adding a polymerization initiator 80 to induce polymerization reaction; and thereby preparing the electrophoretic particles 5 in which the particles 50 are coated with an organic polymer 60. In the method, the charge polarity and the amount of charge of the electrophoretic particles 5 are controlled by setting at least one condition of: the polarity of the polar group 621; the number of the polar groups 621 in the second polymerizable surfactant 62; the valence of the polar groups 621; the molecular weight of the second polymerizable surfactant 62; and an added amount of the second polymerizable surfactant 62.
