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

摘要

The present invention is not like a physical shape or material composition of the surface change even in the durable use, reliable, and can be given a charge to the toner, it is possible to prevent the occurrence of charge-up of toner contamination or toner to form a good image for a long period of time Symptoms can to provide the carrier.; That is, has a resin coating layer formed on at least gas and the substrate surface, the resin coating layer is degree of graphitization p (002) is 0.20 to 0.95 and indentation hardness value HUT [68] of 15 to 60 of the graphitized particles (i), or degree of graphitization p (002) is 0.20 to 0.95 and an average circularity relates to a developer carrying member, characterized in that at least a SF-1 is 0.64 or more graphitized particles (ii).
