Summary:PROBLEM TO BE SOLVED: To provide magnetic toner that provides high-quality images in a high-speed machine, and prevents electrostatic offset.SOLUTION: Magnetic toner includes magnetic toner particles containing a binder resin and a magnetic substance, and inorganic fine powder. The binder resin contains a polyester unit; the magnetic toner has dielectric loss factor at 40°C and 100 kHz of 0.40 pF/m or more and 1.00 pF/m or less, and dielectric loss factor at 150°C and 100 kHz of 0.50 pF/m or more and 4.00 pF/m or less.
