Provided is a toner having excellent environmental stability, durability stability, and low-temperature fixability. A toner containing at least a resin (a) containing polyester as a main component, a colorant and a wax, wherein the toner particles have a glass transition temperature (temperature rising rate measured at 0.5 ° C./min). ° C.) is Tg (0.5), and the glass transition temperature (° C.) measured at a heating rate of 4.0 ° C./min is Tg (4.0), 40.0 ≦ Tg (0. 5) The relationship of ≦ 60.0 and 2.0 ≦ Tg (4.0) −Tg (0.5) ≦ 10.0 is satisfied, and the toner particles are in an environment of 40 ° C. and 95% RH. When the water absorption is 1.5% or less and the acid value of the toner particles is Ut (mgKOH / g), Ut is 0.2 mgKOH / g or more and 1.0 mgKOH / g or less, and the specific surface area of the toner particles Is St (m 2 / g), St is 0.60 m 2 / g or more, 2 It is 0.000 m 2 / g.
