    摘要: Black magnetic toner comprising: a binder resin, and black magnetic composite particles comprising: magnetic iron oxide particles having an average particle diameter of 0.055 to 0.95 &mgr;m; a coating layer formed on the surface of said magnetic iron oxide particles, comprising at least one organosilicon compound selected from the group consisting of: (1) organosilane compounds obtainable from alkoxysilane compounds, (2) polysiloxanes or modified polysiloxanes, and (3) fluoroalkyl organosilane compounds obtainable from fluoroalkylsilane compounds; and a carbon black coat formed on said coating layer comprising said organosilicon compound, in an amount of 1 to 25 parts by weight based on 100 parts by weight of said magnetic iron oxide particles. Such a black magnetic toner can be free from being deteriorated in electric resistance due to the existence of the carbon black coat, and as a result, is suitable as a high-resistance or insulated magnetic toner.

    摘要: A soft magnetic material is a soft magnetic material including a composite magnetic particle (30) having a metal magnetic particle (10) mainly composed of Fe and an insulating coating (20) covering metal magnetic particle (10), and insulating coating (20) contains an iron phosphate compound and an aluminum phosphate compound. The atomic ratio of Fe contained in a contact surface of insulating coating (20) in contact with metal magnetic particle (10) is larger than the atomic ratio of Fe contained in the surface of insulating coating (20). The atomic ratio of Al contained in the contact surface of insulating coating (20) in contact with metal magnetic particle (10) is smaller than the atomic ratio of Al contained in the surface of insulating coating (20). Thus, iron loss can be reduced.
