[PROBLEMS] Providing a charge control agent that has a negative charge providing property at a practical level, is colorless to light-colored and usable in color toners, produces static charges stable to environmental changes by electrifying the resin powder of a toner and the like, is excellent in storage stability and durability, and is highly safe, as well as a method of controlling the charge of resin powder using the charge control agent, and a toner.
[MEANS OF SOLVING THE PROBLEMS] A charge control agent having a compound represented by the formula shown below as the active ingredient, as well as a method of controlling the charge of resin powder using the charge control agent, and a toner.
X : an oxygen atom or N-H;
Each of R1 to R4 : a hydrogen atom, a carboxyl group, an aminocarbonyl group having or not having a substituent, an aminocarbonylmethyl group having or not having a substituent, an alkoxycarbonyl group, an alkyl group, a phenyl group having a substituent or not having a substituent, or a group that forms a saturated or unsaturated ring having or not having a substituent in cooperation with any other group selected from among R1 to R4.
[问题] 提供一种电荷控制剂,该电荷控制剂在实用水平上具有提供负电荷的特性,无色至浅 色,可用于彩色调色剂,通过对调色剂的树脂粉末等通电产生对环境变化稳定的静电荷,储 存稳定性和耐久性优异,安全性高,以及使用该电荷控制剂控制树脂粉末电荷的方法和调色 剂。
[解决问题的方法]一种电荷控制剂,其有效成分为下式所示的化合物,以及一种使用该电荷控制剂控制树脂粉电荷的方法和一种调色剂。
X :氧原子或 N-H;
R1 至 R4 中的每一个:氢原子、羧基、具有或不具有取代基的氨基羰基、具有或不 具有取代基的氨基羰甲基、烷氧基羰基、烷基、具有或不具有取代基的苯基、或与选 自 R1 至 R4 的任何其他基团配合形成具有或不具有取代基的饱和或不饱和环的基团。
