This invention provides a toner that has excellent low-temperature fixation and anti-offset properties, has a wide fixation temperature range, provides a high-gloss fixed image upon fixation and can form a high-quality toner image. The toner comprises toner particles comprising toner mother particles containing a binder resin and a colorant. In the measurement of the toner particles by the flow tester temperature rise method, the toner particles satisfy 0 ≥ AηT ≥ -0.064 wherein AηT represents an average viscosity change level represented by formula: AηT = (log(η110) - log(η100))/(110-100) wherein η100 (Pa·s) represents viscosity at 100ºC, η110 (Pa·s) represents viscosity at 110ºC, and η100 is 15000 to 40000 Pa·s. |
