    • 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.

    • A toner composition for electrophotography comprises, as a principal component, a reaction product of a mixture which comprises 20 to 80% by weight of a polyester resin (A) whose number average molecular weight ranges from 1,000 to 5,000, whose glass transition point ranges from 0.degree. to 50.degree. C. , whose OH value ranges from 20 to 60 KOHmg/g and which is prepared by using at least one trifunctional alcohol in an amount of from 2 to 10 mole % on the basis of the total amount of starting raw alcohols consisting of at least one diol and at least one trifunctional alcohol; and 80 to 20% by weight of a polyester resin (B) whose number average molecular weight ranges from 1,000 to 5,000, whose glass transition point ranges from 50.degree. to 90.degree. C. and whose OH value is not more than 5 KOH mg/g, with a diisocyanate. The toner composition has hot-melt properties suitable for rapid copying, for instance, the lower limit of fixing temperature thereof is low and the temperature range within which the toner can be fixed is very wide. Moreover, the toner composition is excellent in resistance to offset, antiblocking properties, resistance to ADF contamination, pulverization properties and quality of images. Thus, the toner composition shows practically excellent quality as a toner composition for electrophotography.
