调色剂
摘要：
一种包括调色剂颗粒的调色剂，各所述调色剂颗粒含有粘结剂树脂和着色剂，其中所述粘结剂树脂包括在由差示扫描量热计测定的DSC曲线中在55℃至120℃的温度下具有吸热峰的树脂；所述调色剂的软化点Tm为90℃至140℃；在6.28rad/sec频率下测定的调色剂粘弹性特性中，在180℃温度下的贮能弹性模量为1.0×102Pa至1.0×104Pa；在x轴为温度且y轴为损耗角正切tanδ的图表中，tanδ在50℃至70℃范围内具有至少一个具有峰顶的峰；在峰顶温度下的tanδ(P)为2.0至10.0；在峰顶温度下的tanδ(P)与Tm温度下的tanδ(Tm)的比(tanδ(P)/tanδ(Tm))在2.5至8.0的范围内。
摘要（英）：

A toner comprising toner particles, each of which contains a binder resin and a colorant, wherein the binder resin includes a resin having an endothermic peak at a temperature of 55 DEG C to 120 DEG C in a DSC curve; the toner has a softening point Tm of 90 DEG C to 140 DEG C; in the viscoelastic characteristic of the toner measured at a frequency of 6.28 rad/sec, the storage elastic modulus at a temperature of 180 DEG C is 1.0 102 Pa to 1.0 104 Pa; in a chart with the temperature on the x-axis and tand on the y-axis, tand has a peak having a peak top in the range of 50 DEG C to 70 DEG C; tand(P) at the peak top temperature is 2.0 to 10.0; the ratio of the tand (P) at the peak top temperature to tand (Tm) at a temperature of Tm (tand(P) /tand (Tm)) is in the range of 2.5 to 8.0.
