RESIN-FILLED FERRITE CARRIER FOR ELECTROPHOTOGRAPHIC DEVELOPER AND ELECTROPHOTOGRAPHIC DEVELOPER USING THE FERRITE CARRIER |
| 摘要 |
There is provided a resin-filled ferrite carrier for an electrophotographic developer, in which a void of a porous ferrite particle used as a ferrite carrier core material is filled with silicone resin, wherein a true specific gravity (Y) of the porous ferrite particle filled with the silicone resin and a Si/Fe value (X) measured by fluorescent X-ray elemental analysis satisfy the following inequality (1):;−350X≦Y−4.83≦−100X (1). |
