    摘要： 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): 0.1≦η*a≦1.0  (1) 1.1≦η*b/η*a≦3.5  (2)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·) 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.

    摘要翻译： 本发明提供一种用于静电荷图像显影的调色剂，其至少包含粘合剂树脂，着色剂和脱模剂。 脱模剂满足以下等式（1）和（2）：<？in-line-formula description =“In-line Formulas”end =“lead”？> 0.1 <= eta * a <= 1.0（1） ？in-line-formula description =“In-line Formulas”end =“tail”？> <？in-line-formula description =“In-line Formulas”end =“lead”？> 1.1 <= eta * b / eta * a <= 3.5（2）<？in-line-formula description =“In-line Formulas”end =“tail”？>其中eta * a表示从第一动态粘弹性确定的复数粘度（Pa.s） 以6.28rad / s的测定频率进行测定，eta * b表示从脱模剂的测定频率为62.8rad / s的第二动态粘弹性测定值求出的复数粘度（Pa。）， 在比脱模剂的熔点低15℃的温度到比脱模剂的熔点高15℃的温度的温度范围内测量第一动态粘弹性和第二动态粘弹性。
