PROBLEM TO BE SOLVED: To provide a toner composition excellent in an increase in fixing temperature range accompanying improvement in low-temperature fixing property, blocking resistance, and charging stability. In a toner binder composed of a linear polyester resin (A) and a non-linear polyester resin (B), the peak top molecular weight of (A) is 2500 or less, the glass transition temperature [Tg] is 50 to 80 ° C., [Tg ] And the flow softening point [Tm] are Tm−Tg ≦ 35 (° C.) and an acid value of 0 to 20 (mgKOH / g) is used.
