PROBLEM TO BE SOLVED: To provide toner for electrophotography sufficiently electrified, avoiding the omission of an image in transfer and the soiling of the image due to faulty cleaning, realizing the excellent reproducibility of a thin line and halftone, having excellent environment stability and aging stability, eliminating the need of a toner supply mechanism and a toner concentration sensor and realizing miniaturization and inexpensiveness, and two-component developer, an image forming method and an image forming device. SOLUTION: The magnetic toner consisting of at least binding resin and magnetic substance incorporates inorganic impalpable powder whose surface is treated by silicone oil and the magnetization of the magnetic toner is 10 to 25 emu/g in 5 k oersted magnetic field and 7 to 20 emu/g in 1 k oersted magnetic field. |
