Title: Method for manufacturing toner
Inventor: IGAMI ATSUSHI
IPC: G03G9/087
Filed: 2007-01-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing toner by which loss of toner forming materials is reduced and the toner can be manufactured with high production efficiency.  <P>SOLUTION: Toner forming materials are dissolved or dispersed in an organic solvent to prepare an oily component, and the prepared oily component is emulsified in an aqueous medium to prepare an emulsion. In a removal apparatus 1, the prepared emulsion flows down into a flow-down section 7 in such a way that a gas phase exists, and the organic solvent is removed from the flowing emulsion. From the emulsion flowing down in the flow-down section 7, the organic solvent is continuously removed while keeping the liquid level of the emulsion constant in each position in the flow-down direction. As a result, manufacturing efficiency can be enhanced. Since adhesion of the emulsion to a wall surface, etc., due to lowering of the liquid level can be prevented, loss of the toner forming materials can be reduced and the objective toner can be manufactured in a high yield.  <P>COPYRIGHT: (C)2008,JPO&INPIT
