PROBLEM TO BE SOLVED: To provide a polyester resin composition for a nonmagnetic mono-component toner which is used as a binder resin, prevents fogging or a lowered fluidity of the toner, even after repeated developments for a long period of time, its manufacturing method and a nonmagnetic mono-component toner using the polyester resin composition. SOLUTION: The polyester resin composition for a nonmagnetic mono-component toner contains a titanium compound in the amount of 0.005-4wt.%. The titanium compound has a glass transition temperature of 60-75°C, a softening point of 135-155°C and contains 5-30wt.% of a chloroform-insoluble component. The polyester resin composition is obtained by polycondensating the raw material monomer in the presence of the titanium compound. COPYRIGHT: (C)2004,JPO |
