The present invention is to provide a charge controlling agent and negatively chargeable toner that do not contain any toxic metal, are essentially free from the risk of evoking ignition or explosion, and can exhibit a high charge amount and rapid initial increase in charging.
The charge controlling agent is a mono azo iron complex compound represented by Formula (1):
wherein J represents H, alkali metal, ammonium, or alkyl ammonium, or two or more of those elements in combination.
本发明旨在提供一种电荷控制剂和负电荷墨粉,它们不含任何有毒
金属,基本上没有引起燃烧或爆炸的危险,并能表现出较高的电荷量和快速的初始电荷增加。
电荷控制剂是一种由式(1)表示的单偶氮
铁络合物:
其中 J 代表 H、碱
金属、
铵或烷基
铵,或两个或两个以上这些元素的组合。
