Filed: 1990-04-20
Abstract: PURPOSE:To obtain the specific and stable toner which lessens the splashing of fine powder by sticking and fixing very small resin particles by a mechanical impact force, then subjecting the particles to a heat treatment in hot gaseous flow. CONSTITUTION:The fine particles for surface reforming are stuck to the surface of the core particles and the mechanical impact force is imparted thereto; further, the fine particles are heat treated in the hot gaseous flow kept at 200 to 600 deg.C to uniformly fix and/or film the fine particles for surface reforming on the surfaces of the core particles. For example, fine particles 3 of a polymer, a charge control agent 4 and a fluidizing agent 5 are stuck together with the core particles 1 and are immobilized by the mechanical impact force. The particles are then heat treated in the hot gaseous flow, by which the fine particles 3 of the polymer and the constituting resin of the core particles 1 partly melted and stick. The charge control agent 4 and the fluidizing agent 5 are accordingly fixed and stuck securely to the surfaces of the core particles. The generation of problems, such as nonuniformity of the surface reforming, desorption and splashing of the fine particles, image fogging by the toner splashing occurring in the desorption of the fine particles, and staining in a copying machine, is obviated in this way.
