Electrostatic charge image developing carrier, electrostatic charge image developer, process cartridge, image forming apparatus and image forming method

An electrostatic charge image developing carrier comprising:

• a magnetic particle;
• and
• a coating resin layer that covers the magnetic particle and contains a silica particle as an internal additive,
• wherein a ratio of Si on a surface of the coating resin layer, determined by an X-ray photoelectron spectroscopy (XPS), is 6 atom % or more and 12 atom % or less;
• an average particle diameter of the silica particle is 5 nm or more and 70 nm or less;
• a content of the silica particle is 25 mass % or more and 45 mass % or less relative to a total mass of the coating resin layer;
• an average thickness of the coating resin layer is 0.6 μm or more and 1.4 μm or less;
• and
• an average length RSm of a roughness curve element of a surface of the carrier is 0.5 μm or more and 0.8 μm or less;
• an arithmetic average height Ra of a roughness curve of the surface of the carrier is 0.1 μm or more and 1.0 μm or less;
• and
• the arithmetic average height Ra of the roughness curve of the surface of the carrier is different from an arithmetic average height of a roughness curve of a surface of the magnetic particle.
