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. |
