METHOD FOR PRODUCING BINDER RESIN FOR TONER, BINDER RESIN FOR TONER PRODUCED BY THE PRODUCTION METHOD, AND TONER CONTAINING THE BINDER RESIN

摘要

PPROBLEM TO BE SOLVED: To provide a binder resin for toner which has extremely reduced residual volatile components, and also has required characteristics when being made into electrophotographic toner. PSOLUTION: The method for producing a binder resin for toner is characterized in that, by bringing a binder resin for toner containing volatile components into contact with a supercritical fluid source, the residual volatile components in the binder resin for toner are removed. In a preferable implementation, the binder resin for toner is a styrene resin, and the supercritical fluid source is carbon dioxide. PCOPYRIGHT: (C)2010,JPO&INPIT
