摘要： Disclosed is a positively chargeable toner comprising, as a charge-controlling agent, an acid adduct, metal complex or derivative of a 2-alkylimidazole represented by the following formula:
wherein R₂ stands for an alkyl group having 11 through 17 carbon atoms, and R₄ stands for a hydrogen atom or a methyl group.
In this toner, a high charge-controlling effect is attained with a small amount of the charge-controlling agent, and since the charge-controlling agent has a white color or light color, this toner is advantageously used as an electrostatic photographic toner for the color printing.摘要翻译： 公开了一种带正电荷的调色剂，其包含作为电荷控制剂的酸加合物，金属配合物或由下式表示的2-烷基咪唑的衍生物：其中R2表示具有11至17个碳原子的烷基 ，R4表示氢原子或甲基。 在该调色剂中，通过少量的电荷控制剂获得高的电荷控制效果，并且由于电荷控制剂具有白色或浅色，因此该调色剂有利地用作静电照相调色剂 彩色印刷。
