More Information
Summary:The magnetic toner contains: magnetic toner particles containing a binder resin and a magnetic body; and inorganic fine particles present on the surface of the magnetic toner particles, wherein the inorganic fine particles present on the surface of the magnetic toner particles comprise strontium titanate fine particles and metal oxide fine particles, and the metal oxide fine particles containing silica fine particles, and optionally containing titania fine particles and alumina fine particles, and a content of the silica fine particles being at least 85 mass% with respect to a total mass of the silica fine particles, the titania fine particles and the alumina fine particles. In addition, the magnetic toner has a characteristic state of coverage, by the inorganic fine particles, of the magnetic toner particle surface, and the ratio [D4/D1] of the weight-average particle diameter (D4) to the number-average particle diameter (D1) is in a prescribed range.
