An electrophotographic toner includes capsule toner particles that each include an anionic toner core having a zeta potential at pH 4 of no greater than -5 mV and a cationic shell layer disposed over a surface of the toner core. Each of the capsule toner particles has, at a surface thereof, a sodium concentration of no less than 200 ppm and no greater than 1,000 ppm as measured by an ICP spectrometer. |
