Abstract
A carrier for developing an electrostatic latent image includes carrier particles, and the carrier particles include magnetic particles and a coating layer coating the surfaces of the magnetic particles. The BET specific surface area of the magnetic particles is 0.1300 m2/g to 0.2500 m2/g, and the difference in BET specific surface areas obtained by subtracting the BET specific surface area of the magnetic particles from the BET specific surface area of the carrier particles is 0.0300 m2/g to 0.400 m2/g.
