Abstract:
1. A developer manufacturing method, comprising the steps of: providing a reactor comprising a stirring mechanism, a mechanism for discharging dissolved components and a developer material carrier comprising a plurality of sheets of mesh that prevents the passage of treated materials and allows the passage of the supercritical or subcritical fluid, the stirring mechanism being disposed within the developer material carrier; dissolving a binding resin component in a supercritical or subcritical fluid so that the binding resin component is blended with a coloring agent component; and reducing the solubility of the binding resin component in the supercritical or subcritical fluid so that the binding resin component is precipitated in the form of particles with the coloring agent component dispersed in the interior of the binding resin component, wherein the plurality of sheets of mesh provides a more uniform discharge of dissolved resin and dispersed coloring agent and developer having a desired particle diameter.
