An electrostatic charge image developing carrier capable of obtaining a clear image even in a low density image without lowering charging ability, and an electrostatic charge image developing developer and electrostatic charge image developing using the same. An agent cartridge, a process cartridge, and an image forming apparatus are provided. A magnetic particle and a coating layer covering the surface of the magnetic particle, wherein the magnetic particle has a BET specific surface area of 0.1300 m 2 / g or more and 0.2500 m 2 / g or less, and the coating layer A carrier for developing an electrostatic charge image, wherein a difference obtained by subtracting the BET specific surface area of the magnetic particles from the BET specific surface area of the magnetic particles coated with a magnetic particle is 0.0300 m 2 / g or more and 0.400 m 2 / g or less And an electrostatic charge image developing developer, an electrostatic charge image developing developer cartridge, a process cartridge, and an image forming apparatus using the same.
