Title: Production of electrophotographic toner binder
Inventor: NISHIDA MASAHARU
IPC: G03G9/087
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of molecular weight and to efficiently carry out production in a short time when a toner binder having a wide molecular weight distribution is produced by mixing and dissolving powdery resins in an aromatic solvent as a good solvent in the presence of a bad solvent. SOLUTION: Powdery resins are mixed and dissolved in an aromatic solvent as a good solvent for the resins in the presence of a bad solvent which does not substantially dissolve the resins. Since the powdery resins are wetted with the bad solvent, the resins are not substantially dissolved in the aromatic solvent until they are finely dispersed in the aromatic solvent and the formation of undissolved lumps is prevented. The objective toner binder having a wide molecular weight distribution is efficiently obtained in a short time. The powdery resins are obtained by polymerizing styrenes and/or (meth)acrylic esters.
