ABSTRACT:
The present invention provides a method for producing a carrier that includes dissolving at least a coating material in carbon dioxide in a liquid state, and forming a coating layer on a core material surface by reducing the solubility of the liquid with at least the coating material dissolved therein through control of at least any one of the pressure and temperature. The present invention also provides a carrier produced by the method for producing a carrier.
