Zusammenfassung:To provide a carrier for electrostatic charge image development excellent in charge maintainability of toner.SOLUTION: A carrier for electrostatic charge image development has a magnetic particle and a coating resin layer that covers the magnetic particle and includes inorganic particles. When A is the net intensity of Si when X-ray fluorescence analysis is performed on a carrier A extracted from a developer A obtained by mixing a toner externally added with silica particles and a carrier, B is the net intensity of Si when X-ray fluorescence analysis is performed on a carrier B extracted from a developer B obtained by adding silica particles to the developer A and stirring the developer in a TURBULA stirrer for 20 minutes, and C is the net intensity of Si when X-ray fluorescence analysis is performed on a carrier C extracted from a mixture C obtained by stirring the carrier B extracted from the developer B and toner particles in the TURBULA stirrer for 2 minutes, the formula 1: 0
