    • A polyester resin for toner, wherein an acid component of the polyester comprises (1) disproportionated rosin and (2) terephthalic acid and/or isophthalic acid, an alcohol component of the polyester comprises (3) glycidyl ester of tertiary fatty acid and (4) an aliphatic diol containing from 2 to 10 carbon atoms, and a cross-linking component of the polyester comprises a polycarboxylic acid having three or more carboxyl groups and/or a polyol having three or more hydroxyl groups, with the molar ratio of the acid component (1) to the acid component (2), (1)/(2), being from 0.2 to 0.6 and the molar ratio of the alcohol component (3) to the alcohol component (4), (3)/(4), being from 0.05 to 0.4. A toner for developing an electrostatic charge image contains the polyester resin for a toner (binder resin), a colorant and a charge control agent. Further, the invention also relates to an image-forming method using the toner for developing an electrostatic charge image.
    • 1.一种调色剂用聚酯树脂,其中,所述聚酯的酸成分包含(1)歧化松香和(2)对苯二甲酸和/或间苯二甲酸,所述聚酯的醇成分包含(3)叔脂肪酸的缩水甘油酯和(4 )含有2至10个碳原子的脂族二醇,并且所述聚酯的交联组分包含具有三个或更多个羧基的多元羧酸和/或具有三个或更多个羟基的多元醇,所述酸的摩尔比 组分(1)与酸组分(2),(1)/(2)的摩尔比为0.2至0.6,醇组分(3)与醇组分(4),(3)/ ),为0.05〜0.4。 用于显影静电荷图像的调色剂包含用于调色剂的聚酯树脂(粘合剂树脂),着色剂和电荷控制剂。 此外,本发明还涉及使用用于显影静电荷图像的调色剂的图像形成方法。
