摘要：
A carrier is provided. The carrier includes a particulate magnetic core, and a cover layer located on the surface of the particulate magnetic core and including a resin and a filler. When determined from observation of cross-section of the carrier, the shape factor SF2 of the carrier is from 120 to 160, the ratio of the average domain diameter of the particulate magnetic core to the number average particle diameter of the filler is from 1:1 to 1:0.003, and the area ratio of the filler in the cover layer is from 30 to 85%.
