PROBLEM TO BE SOLVED: To provide a resin composition useful as a binding resin for a toner, having both excellent durability and fixity; and to provide a binding resin for the toner containing the resin composition, and the toner containing the binding resin. SOLUTION: The resin composition is obtained by reacting a poly(2-4C)alkylene terephthalate having≥200°C melting point, with a low-molecular polyester having 400-2,500 number average molecular weight, and has 80-165°C softening point. The resin composition is also obtained by reacting the polyalkylene (having 2-4 carbons) terephthalate having≥200°C melting point, with the low-molecular polyester having 400-2,500 number average molecular weight and a tri-or more-valent monomer, and has 80-165°C softening point. The binding resin for the toner contains the resin composition. The toner contains the binding resin. COPYRIGHT: (C)2004,JPO |
