PROBLEM TO BE SOLVED: To provide a magnetic toner which satisfies low-temperature fixability and high-temperature offset resistance highly, maintains high developability even under severe environment, and does not generate sleeve ghost. . A magnetic toner containing at least a binder resin, magnetic iron oxide, and two or more hydrocarbon waxes, wherein at least one of the hydrocarbon waxes (a) has a hydroxyl group value (H V) is 5 150 mgKOH / g, and an ester value (E V ) of 1 ５０50 mgKOH / g, and the relationship is H V > E V , and at least one type of hydrocarbon wax (b) Is a hydrocarbon wax selected from polyolefin wax, Fischer-Tropsch wax and paraffin wax. |
