A developer carrier comprising a cylindrical support having provided on the outer surface thereof a coating layer for retaining a developer, wherein the coating layer comprises electrically conductive fine particles and a binder resin comprising a phenolic resin having a weight-average molecular weight of from 3,000 to 5,000 as determined before being crosslinked. Also disclosed is a developing apparatus which comprises a developer carrier for retaining a developer on the surface thereof and for conveying the developer onto the position at which an electrostatic latent image formed on a latent image carrier is developed, wherein the developer carrier comprises a cylindrical support having provided on the outer surface thereof a coating layer for retaining a developer, wherein the coating layer comprises electrically conductive fine particles and a binder resin comprising a phenolic resin having a weight-average molecular weight of from 3,000 to 5,000 as determined before being crosslinked.
