Magnetic toner

A magnetic toner, comprising:

• magnetic toner particles each comprising at least a binder resin, an iron oxide and a sulfur-containing polymer, and inorganic fine powder blended with the magnetic toner particles;
• wherein
• the magnetic toner particles have a weight-average particle size (D4) of 3-10 μm,
• the magnetic toner particles retain carbon in an amount of A and iron in an amount of B at surfaces thereof as measured by X-ray photoelectron spectroscopy, satisfying:
• B/A<0.001,
• the magnetic toner particles retain carbon in an amount of A and sulfur in an amount of E at surfaces thereof as measured by X-ray photoelectron spectroscopy, giving a ratio E/A in a range of 0.0003-0.0050, and
• the magnetic toner contains at least 50% by number of magnetic toner particles satisfying a relationship of D/C≦0.02, wherein C represents a projection area-equivalent circle diameter of each magnetic toner particle, and D represents a minimum distance between a surface of the magnetic toner particle and iron oxide particles contained in the magnetic toner.
