摘要:
There are adopted an electrophotographic resin-coated ferrite carrier having a carrier core coated with a resin, wherein a product of an apparent density ρ (g/cm3), average particle size d (μm) and BET specific surface area S (m2/g) of the carrier core satisfies the following condition, a method for producing the same, and an electrophotographic developer. 4.5≦ρ×d×S≦8.5 (20≦d≦45)
