静电荷图像显影用白色调色剂及图像形成方法
摘要：
本发明的课题在于，提供即使在高应力的状况下也能够提供长期极其稳定的高画质的全彩色图像的静电荷图像显影用白色调色剂。本发明的静电荷图像显影用白色调色剂含有包含调色剂母体粒子和外添剂的调色剂粒子，所述调色剂母体粒子含有粘结树脂、白色着色剂及脱模剂，所述静电荷图像显影用白色调色剂含有体积基准的中值粒径在0.5～1.5μm的范围内的脂肪酸金属盐粒子作为外添剂，调色剂粒子的平均圆度在0.870～0.950的范围内。
摘要（英）：

An object of the invention is to provide a white toner for electrostatic charge image development which can provide a highly stable high-quality full color image for a long period even under high stress condition. The white toner for electrostatic charge image development contains a toner particle that includes a toner base particle containing a binder resin, a white colorant, and a releasing agent, and an external additive, wherein the white toner for electrostatic charge image development contains, as the external additive, a fatty acid metal salt particle having a volume-based median diameter in a range of 0.5 to 1.5 [mu]m, and an average circularity of the toner particles is in a range of 0.870 to 0.950.
