Resin-filled carrier for electrophotographic developer, and electrophotographic developer using the resin-filled carrier

摘要

A resin-filled carrier for an electrophotographic developer obtained by filling resin into voids of a porous ferrite core material, wherein the porous ferrite core material has a pore volume of 0.04 to 0.16 mL/g and a peak pore size of 0.9 to 2.0 μm, and an electrophotographic developer using this resin-filled carrier.
