ELECTROSTATIC CHARGE IMAGE DEVELOPING CARRIER, METHOD OF PREPARING ELECTROSTATIC CHARGE IMAGE DEVELOPING CARRIER, AND ELECTROSTATIC CHARGE IMAGE DEVELOPER

摘要

An electrostatic charge image developing carrier includes magnetic particles and a resin coating layer which covers the magnetic particles, wherein a sulfate ion concentration of the resin coating layer is 0.05% by weight or less with respect to a total weight of the resin coating layer, and when a total value of a molar amount of sulfate ions contained and a molar amount of sulfo groups contained per 1 g of the resin coating layer is A mol and a molar amount of sodium ions contained per 1 g of the resin coating layer is B mol, a relationship of 0.1B/A1.2 is satisfied.
