调色剂、显影剂和图像形成设备
摘要：
一种调色剂，其包括：颜料；不溶于四氢呋喃(THF)的聚酯树脂A；和能溶于THF的聚酯树脂B，其中所述调色剂满足以下要求(1)‑(3)：(1)所述聚酯树脂A包括一种或多种具有3‑10个碳原子的脂族二醇作为构成所述聚酯树脂A的组分；(2)所述聚酯树脂B至少包括40摩尔％或更大的量的亚烷基二醇作为构成所述聚酯树脂B的组分；和(3)所述调色剂在所述调色剂的差示扫描量热法(DSC)中的第一次加热时的玻璃化转变温度(Tg1st)为20℃‑50℃。
摘要（英）：

A toner that contains a pigment, a polyester resin (A) that is insoluble in tetrahydrofuran (THF), and a polyester resin (B) that is soluble in THF. Said toner also satisfies the following conditions: (1) the former polyester resin (A) contains a C3-10 aliphatic diol as a constituent; (2) the latter polyester resin (B) contains at least 40 mol% of an alkylene glycol as a constituent; and (3) differential scanning calorimetry (DSC) indicates that the glass transition temperature (Tg1st) of the toner when the temperature of the toner is raised for the first time is in the 20-50 DEG C range.
