ABSTRACT:
A carrier for a two-component developer for electrostatic latent images which comprises carrier particles whose surfaces are coated with a resin layer comprising a thermosetting resin, wherein the resin layer formed on convex parts of the carrier particles is relatively thin compared to that formed on the concave parts, and wherein the ratio of the total area of the thin resin layer to the total surface area of the carrier particles is from about 55% to about 90%. The resin coated carrier is manufactured by a coating liquid including the thermosetting resin on carrier particles and drying the coated liquid by either a dip coating, a spray coating or a drip coating method, under reduced pressure while heating.
