| abstract | PROBLEM TO BE SOLVED: To provide a carrier for electrophotographic image formation, which has excellent durability, suppresses the generation of color stains, and obtains stable image quality even when used for a long period of time. SOLUTION: The core material particles and a coating layer for coating the surface of the core material particles are included, and the core material particles have an apparent density of 2.0 [g/cm 3 ] or more and 2.2 [g/cm 3 ] or less. And Mn-based ferrite particles having a magnetization in the magnetic field of 500 [Oe] of 44 [emu/g] or more and 52 [emu/g] or less, and the coating layer is at least carbon black and two kinds of inorganic fine particles A and B. And the coating layer, the inorganic fine particles A and the carbon black has a concentration gradient in the thickness direction, the concentration of the inorganic fine particles A is higher toward the surface layer of the coating layer, and the carbon black of The above problem is solved by the electrophotographic image forming carrier having a low density.
