CARRIER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE AND METHOD FOR PRODUCING THE SAME, ELECTROSTATIC CHARGE IMAGE DEVELOPER, PROCESS CARTRIDGE, IMAGE FORMING APPARATUS, AND IMAGE FORMING METHOD

A carrier for developing an electrostatic charge image includes magnetic particles and a resin coating layer covering the magnetic particles, the resin coating layer containing inorganic particles. The ratio M1/M2 is 0.8 or more and 1.2 or less, where M1 is the concentration of the inorganic particles in the resin coating layer within a distance of 300 nm from the carrier surface, and M2 is that within a distance of 300 nm from the surface of the resin coating layer closer to the magnetic particle, and the percentage surface exposure of the magnetic particles is 0% by area or more and 5% by area or less. A cavity lies at least in part between the resin coating layer and a surface of the magnetic particles, and the average width, or the average length parallel to the thickness of the resin coating layer, of the cavity is 50 nm or more and 500 nm or less.
