Abstract
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. The coverage ratio of the magnetic toner particle surface by the inorganic fine particles resides in a prescribed range for this magnetic toner; the binder resin is a styrene resin; the weight-average molecular weight and radius of gyration of the magnetic toner reside in a prescribed relationship; and the viscosity of the magnetic toner at 110° C. resides in a prescribed range.
