PROBLEM TO BE SOLVED: To provide a magnetic toner having excellent charge rising property even after long-term storage and having a broad fixation temperature region.SOLUTION: The magnetic toner comprises magnetic toner particles containing a binder resin and a magnetic material, and inorganic fine particles, and has an average circularity of 0.955 or more. When the inorganic fine particles are classified, based on fixing strength thereof to magnetic toner particles and in ascending order of the fixing strength, into low fixation strength inorganic fine particles, middle fixation strength inorganic fine particles, and high fixation strength inorganic fine particles, the content of the low fixation strength inorganic fine particles, a ratio of the middle fixation strength inorganic fine particles to the low fixation strength inorganic fine particles, and a coverage ratio X of the high fixation strength inorganic fine particles on surfaces of the magnetic toner are within specific ranges. |
