(57) [Summary] [Problem] To exhibit stable charging characteristics regardless of the environment, An object of the present invention is to provide a magnetic toner capable of giving a high quality image. SOLUTION: A magnetic toner particle containing at least a binder resin, a polymer having an iron oxide and a sulfur atom, and a magnetic toner having an inorganic fine powder mixed with the magnetic toner particle: Weight average particle size (D4) is 3-10μ ii) the average circularity of the magnetic toner is 0.970 or more; iii) the magnetic field of the magnetic toner of 79.6 kA / m (100 0 Oersted) with a magnetization intensity of 10 to 50 Am 2 / kg (emu / g). |
