    • Provided is a toner satisfying low-temperature fixing performance and long-term storage stability of fixed images. Further, provided is a toner capable of obtaining toner images excellent in long-term storage stability irrespective of use environments even in the case where images are formed by a high-speed fixing system having low internal pressure of a fixing nip of a fixing device and a high printing speed. The toner includes toner particles containing a binder resin having a resin A and B, and a coloring agent, in which the resin A includes a resin including a moiety capable of forming a crystalline structure; the resin B includes a resin free of a moiety capable of forming a crystalline structure; and ΔHhigh and ΔHlow satisfy the expressions: 2≦ΔHhigh≦45 3[%]≦{(ΔHlow−ΔHhigh)/ΔHlow}×100≦70[%] where ΔHhigh and ΔHlow represent a heat of melting derived from the binder resin measured at a temperature increase speed of 100° C./min and 10° C./min, respectively.
    • 提供了满足固定图像的低温定影性能和长期保存稳定性的调色剂。 此外,提供一种调色剂,即使在通过定影装置的定影辊隙的内部压力低的高速定影系统形成图像的情况下,也可以获得长期保存稳定性优异的调色剂图像, 印刷速度高。 调色剂包括含有具有树脂A和B的粘合剂树脂和着色剂的调色剂颗粒,其中树脂A包括包含能够形成结晶结构的部分的树脂; 树脂B包括不含能够形成结晶结构的部分的树脂; 和&Dgr; Hhigh和&Dgr。Hlow满足表达式:2≦̸&Dgr; Hhigh≦̸ 45 3 [%]≦̸ {(&Dgr; Hlow-&Dgr; Hhigh)/&Dgr; Hlow}×100≦̸ 70 [%] 高温和低温分别表示以100℃/分钟和10℃/分钟的升温速度测量的粘合剂树脂的熔融热。
