DEVELOPER CARRIER, AND DEVELOPING DEVICE AND PROCESS CARTRIDGE USING DEVELOPER CARRIER

摘要

PROBLEM TO BE SOLVED: To provide a developer carrier constituted so that the physical shape of its surface and the composition of material may not be changed even in the case of endurable service, stably electrifying toner over a long term and preventing soiling by toner and the charge-up of the toner. SOLUTION: The developer carrier carrying developer for making an electrostatic latent image carried on an electrostatic latent image carrier visualizable has at least base substance and a resin coating layer formed on the surface of the base substance, and the resin coating layer incorporates at least graphitized particles whose graphitization degree p (002) is 0.20 to 0.95, and whose indentation hardness value HUT[68] is 15 to 60.
