| abstract | Magnetic toner comprising: a magnetic toner particle that a binder resin and contains a magnetic body, and inorganic fine particles fixed to the surface of the magnetic toner particle, wherein, when the inorganic fine particles are in accordance with their fixing strength to the magnetic toner particle and in the order of weakness of the fixing strength, as weakly fixed inorganic fine particles, medium-fixed inorganic fine particles and strongly fixed inorganic fine particles are classified, 1) the content of the weakly fixed inorganic fine particles is from at least 0.10 part by mass to not more than 0.30 part by mass in 100 parts by mass of the magnetic toner; 2) the medium-fixed inorganic fine particles are at least 2.0 times to not more than 5.0 times that of the weakly-fixed inorganic fine particles; and 3) the coverage ratio X of the coverage of the magnetic toner surface by the highly fixed inorganic fine particles as determined by an X-ray photoelectron spectrometer (ESCA) is from at least 60.0 area% to not more than 90.0 area%, and wherein the weakly-fixed inorganic fine particles are inorganic fine particles which peel off when a dispersion formed by adding the magnetic toner to a surfactant-containing ion-exchanged Water is prepared, shaking for 2 minutes at a shaking speed of 46.7 cm / sec and a shaking amplitude of 4.0 cm; the medium-fixed inorganic fine particles are inorganic fine particles which are not peeled off by shaking but peeled off by ultrasonic dispersion for 30 minutes at an intensity of 120 W / cm 2; and the strongly fixed inorganic fine particles are inorganic fine particles which are not peeled off by the shaking and the ultrasonic dispersion. |
