调色剂
摘要：
本发明涉及调色剂。一种调色剂，其包括含有粘结剂树脂和脱模剂的调色剂颗粒，其中所述调色剂颗粒具有含有有机硅聚合物的表面层；和调色剂颗粒的背散射电子图像的亮度直方图具有两个峰值P1和P2以及P1和P2之间的极小值V，P2源自所述有机硅聚合物，给予P1和P2的亮度在特定范围内，P1和P2的百分比各自为0.50％以上，使用V处的亮度Bl作为参照点，且A1、AV和A2满足特定的关系，其中A1为亮度范围0至(Bl–30)处的总像素数，AV为亮度(Bl‑29)至(Bl+29)处的总像素数，和A2为亮度(Bl+30)至255处的总像素数。
摘要（英）：

Provided is a toner containing a colorant and a binder resin, wherein, in a wettability test of the toner with respect to a methanol/water mixed solvent, the methanol concentration when the transmittance of light at a wavelength of 780 nm is 50% is at least 5.0 volume % and not more than 30.0 volume %, and the interparticle force measured by rupturing a consolidation of the toner formed by compression of the toner with a load of 78.5 N is at least 1.0 nN and not more than 25.0 nN.
