<p>PROBLEM TO BE SOLVED: To provide a binder resin composition for a toner, which can achieve both of low-temperature fixability and heat-resistant storage property and durability of a toner to be obtained, and to provide a production method of the binder resin composition, and a toner for electrostatic charge image development comprising the binder resin composition.SOLUTION: The binder resin composition for a toner comprises one or more kinds of amorphous polyesters and a crystalline polyester, in which at least one amorphous polyester is obtained by reacting an alcohol component, a carboxylic acid component and polyethylene terephthalate. The composition contains the crystalline polyester in an amount 0.3 to 2.5 times the mass of a polyethylene terephthalate-derived component in the amorphous polyester. A production method of the binder resin composition, and a toner for electrostatic charge image development comprising the binder resin composition are also disclosed.</p> |
