| 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 silica particles. The ratio of Si in a surface of the coating resin layer determined by X-ray photoelectron spectroscopy (XPS) is 6 atom% or more and 12 atom% or less.SELECTED DRAWING: None
