| titleOfInvention | Toner composition for electrophotography |
| abstract | The present invention provides a toner composition mainly comprising a binder resin (D) which contains at least 20% by weight of an urethane-modified polyester resin (C) obtained by reacting a polyester resin (A) with an isocyanate compound (B) and whose gel fraction ranges from 2 to 75% by weight. The toner composition exhibits good melting properties upon heating suitable for fast reproduction such as a low lower limit of the fixing temperature and a wide range for permitted fixing temperature and is further excellent in resistance to blocking, resistance to carrier contamination and image-forming properties. The binder resin as the main component of the toner composition can be prepared according to a method comprising the step of continuously adding an isocyanate compound (B) to a polyester resin (A) in an equivalent ratio, NCO/OH, of the amount of the NCO groups of the isocyanate compound (B) to that of OH groups of the polyester resin (A) ranging from 0.3 to 1.00 with kneading to react them, in a kneading means having a built-in screw. |
