    Abstract: The present invention provides a toner for electrophotography capable of achieving high color reproducibility in a wide brightness region ranging from high to low brightness. This toner for electrophotography containing a compound represented by general formula (X-1) is characterized in that when the toner image formed exclusively from the toner is at maximum saturation, the hue angle (H) of the toner in a CIE L*a*b* color space is within the range of 341°≦H≦351°. [Formula 1] (In the formula: one of Rx1 and Rx2 is a methyl group or an ethyl group, while the other represents an alkyl group with C12 or less optionally substituted by a group including an oxygen atom, or a 5- or 6-membered aliphatic ring optionally substituted by a group including an oxygen atom connecting a nitrogen atom and Rx1 and Rx2; and GX2 represents an alkyl group optionally substituted by a group including an oxygen atom.)

    Abstract translation: 本发明提供一种能够在从高亮度到低亮度的宽亮度区域中实现高色彩再现性的电子照相用调色剂。 该含有通式（X-1）表示的化合物的电子摄影用调色剂的特征在于，当由调色剂专门制成的调色剂图像处于最大饱和时，CIE L * a *中调色剂的色调角（H） b *颜色空间在341°@ H @ 351°的范围内。 [式1]（式中，Rx1和Rx2中的一个是甲基或乙基，而另一个表示任选被包含氧原子的基团取代的具有C 12或更小的烷基，或者是5或6 任选被包括连接氮原子的氧原子和Rx1和Rx2的基团取代的脂族环; GX2表示任选被包含氧原子的基团取代的烷基）。
