Abstract:
A magnetic toner including at least: a binder resin; and a magnetic body, in which, when magnetization at a magnetic field strength of 397.9 kA/m and a coercive force of the magnetic toner are denoted by σs (Am2/kg) and Hc (kA/m), respectively, a magnetic field strength at which the magnetic toner shows a magnetization value equal to 95% of σs is denoted by H95% (kA/m), and a number average particle size of the magnetic body is denoted by d (μm), H95%, Hc, and d satisfy the following expressions. 151
