The present invention relates to a resin filling for an electrophotographic developer that can obtain a desired charge amount while maintaining the advantages of a resin-filled carrier while maintaining the advantages of a resin-filled carrier and that has a small environmental fluctuation of the charge amount. To provide an electrophotographic developer using a mold carrier and the resin-filled carrier. A resin-filled carrier for an electrophotographic developer obtained by filling a void in a porous ferrite core material with a resin, wherein the Cl concentration measured by the elution method of the porous ferrite core material is 10 to 10. The resin-filled carrier for an electrophotographic developer, which is 280 ppm and the resin contains an amine compound, and the electrophotographic developer using the resin-filled carrier are employed.
