发明名称 CARRIER FOR TWO-COMPONENT DEVELOPER, ELECTROSTATIC LATENT IMAGE DEVELOPER USING THE SAME, COLOR TONER DEVELOPER, DEVELOPER TO BE SUPPLIED, IMAGE FORMING METHOD, PROCESS CARTRIDGE WITH ELECTROSTATIC LATENT IMAGE DEVELOPER, AND IMAGE FORMING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a carrier for electrostatic latent image development which is used for two-component developer to be used for electrophotography/electrostatic recording to increase durability, and to provide electrostatic latent image developer using the carrier, color toner developer, developer to be supplied, an image forming method, a process cartridge with the electrostatic latent image developer, and an image forming device.SOLUTION: A carrier for electrostatic latent image developer comprises: a magnetic core material particle; and a resin layer covering the surface thereof, the resin layer containing a conductive fine particle. The conductive fine particle is formed by coating white inorganic pigment with phosphor-doped tin or tungsten-doped tin as a conductive material. A ratio of phosphor or tungsten doped with respect to tin in the conductive material is 0.010-0.100.
