<p>[PROBLEMS] To provide a toner for electrostatic charge image development that even in high-speed printing, enables low-temperature fixation, having excellent anti-hot-offset property and that excels in durability and storability. [MEANS FOR SOLVING PROBLEMS] There is provided a toner for electrostatic charge image development comprising colored resin particles comprising a binder resin, a colorant, a charging control agent and a release agent, characterized in that (1) the colored resin particles have a volume average particle diameter (Dv) of 4 to 9 mum, (2) the colored resin particles have an average circularity of 0.93 to 0.995, (3) the shear viscosity (eta1) thereof at 130°C and at a shear rate of 10 /s is in the range of 800 to 3500 Pa s, and (4) the shear viscosity (eta2) thereof at 130°C and at a shear rate of 500 /s is in the range of 100 to 1000 Pa s.</p> |
