ABSTRACT:
The present invention provides a toner for electrostatically charged image development comprising at least a binder resin, a colorant and a releasing agent. The releasing agent satisfies the following equations (1) and (2):in-line-formulae description="In-line Formulae" end="lead"?0.1≦η*a≦1.0 (1)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?1.1≦η*b/η*a≦3.5 (2)in-line-formulae description="In-line Formulae" end="tail"?wherein η*a represents a complex viscosity (Pa·s) determined from a first dynamic viscoelasticity measurement at a measuring frequency of the releasing agent of 6.28 rad/s, η*b represents a complex viscosity (Pa·s) determined from a second dynamic viscoelasticity measurement at a measuring frequency of the releasing agent of 62.8 rad/s, and each of the first and second dynamic viscoelasticities is measured in a temperature range from a temperature that is 15° C. lower than the melting point of the releasing agent to a temperature that is 15° C. higher than the melting point of the releasing agent.
