This is an improved, both in performance and cost, one-step, coated carrier for carrying electropositive toner in electrophotographic developing. The carrier is formed of a suitable core material, such as steel shot, which is coated with an improved, mixed resin system. The improved resin system includes fluorocarbons, such as polytetrafluoroethylene (PTFE) and/or fluorinated ethylene propylene (FEP), dispersed in a polyamide (imide) resin binder. The mixed fluoropolymers in the polyamide (imide) resins are coated onto the steel core in a fluidized bed process.
