Toner kit and color-image-forming method
摘要：
In a toner kit having i) a non-magnetic black toner having at least carbon black and ii) color toners, the black toner has a weight-average particle diameter represented by D4b and a one-point method BET specific surface area represented by Sb, and the color toners, other than the-black toner, each have a weight-average particle diameter represented by D4c and a one-point method BET specific surface area represented by Sc, where the black toner and color toners satisfy the following relations (1) and (2): 0.60≦D4.c/D4b≦0.96,:  Relation (1) 0.750≦Sc/Sb≦1.000;:  Relation (2) and each have an average circularity of from 0.950 to 1.000 and a circularity standard deviation of less than 0.040 as measured with a flow type particle image analyzer.
摘要（中）：

在具有i）至少具有炭黑的非磁性黑色调色剂和ii）彩色调色剂的调色剂试剂盒中，黑色调色剂具有由D 4 b表示的重均粒径和表示的一点法BET比表面积 除了黑色调色剂之外的颜色调色剂各自具有由D4c表示的重均粒径和由Sc表示的单点法BET比表面积，其中黑色调色剂和彩色调色剂满足以下 关系（1）和（2）：<？in-line-formula description =“In-line Formulas”end =“lead”？> 0.60 <= D4.c / D4b <= 0.96，关系（1） in-line-formula description =“In-line Formulas”end =“tail”？> <？in-line-formula description =“In-line formula”end =“lead”？> 0.750 <= Sc / Sb <= 1.000 ;:关系（2）<？in-line-formula description =“在线公式”end =“tail”？>，平均圆形度为0.950〜1.000，圆形标准偏差小于0.040 用流式粒子图像分析仪测量 。
