摘要： A carrier for an electrostatic latent-image developer, comprising a core material having thereon a coating layer comprising a resin and fine electroconductive particles, the resin having a work function of 4.5 eV or lower. An electrostatic latent-image developer comprising the carrier and a toner and an image forming process are also disclosed. The carrier is capable of maintaining a high build-up speed of electrification and a proper electrification level even when a charge control agent is omitted or used in a slight amount or when the addition amount of an additive such as silica and titanium oxide is reduced so as to prevent carrier fouling with a charge control agent or an external additive and to inhibit a decrease in developer life.
