METHOD AND DEVICE FOR COATING PARTICLES, AND CARRIER FOR USE IN DEVELOPER

摘要

A method for coating particles with a coating liquid including supplying airflow to fluidize the particles; mixing the coating liquid with a spray gas in a two-fluid spray nozzle to form a two-phase flow; and atomizing the two-phase flow with the spray gas to spray a mist of the coating liquid upon the particles. A coating device including a vessel; a fluidizing device configured to supply airflow to fluidize a powder in the vessel; and a spray nozzle configured to mix the coating liquid with a spray gas to form a two-phase flow, and to atomize the two-phase flow with the spray gas to spray a mist of the coating liquid. A particulate carrier for use in electrophotographic developer including particles of a core material and a cover layer thereon and prepared by the coating method mentioned above.
