Abstract
A carrier for a developer of an electrostatic latent image, the carrier including: core particles having magnetism; and a coating layer coating a surface of each of the core particles, wherein the coating layer includes two or more kinds of inorganic particles, at least one kind of inorganic particles among the two or more kinds of inorganic particles is inorganic particles A having conductivity and a peak particle diameter of from 300 nm through 1,000 nm, and surface roughness of the carrier calculated by Formula 1 below is from 1.10 m2/g through 1.90 m2/g, C−F Formula 1 where C is a BET specific surface area (m2/g) of the carrier and F is a BET specific surface area (m2/g) of the core particles.
