摘要:
A novel carrier material useful in conjunction with a toner for preparing a two-component developer for electrophotographic processes is provided. The carrier comprises a spherical magnetite particulate material having a reduced metallic iron outer layer which is coated with an outermost resinous layer for conditioning the copying properties of the carrier.

摘要:
A noval carrier powder for electrophotographic developers is provided. The carrier powder comprises spherical magnetite particles having a wustite (FeO) content of less than 10% by weight, a particle diameter of 30-200 .mu.m and a surface porosity of less than 20%.
摘要:
A carrier for use as a component in electrophotographic two-component developers which is improved in durability of the triboelectric property by coating the surface of the iron core particles of carrier with a resinous composition comprised essentially of an epoxy-hydroxy hydrocarbon resin and an acrylic resin.
