PURPOSE:To ensure stable triboelectrifiability and good fluidity and abrasion resistance by coating core particles with a coating layer made of a vinylidene fluoride copolymer having functional groups. CONSTITUTION:The coating layer is formed by coating the core particles with a coating material contg. a vinylidene fluoride copolymer having functional groups or a mixture of F-contg. copolymer and an acrylic resin contg. a cross- linking agent by the spray coating process, and hardening it, thus permitting the carrier to control triboelectrifiability of a toner and to lower critical surface tension and friction coefft. |
