A process for forming non-spherical toner particles by limited coalescence comprises: forming an organic phase comprising a polymeric material, a pigment, a quaternary ammonium tetraphenylborate salt, and a water-immiscible liquid; dispersing the organic phase in an aqueous phase containing a solid colloidal stabilizer; forming a suspension of small droplets of the organic phase in the aqueous phase by high shear agitation; removing the water-immiscible liquid from the small droplets, thereby forming a suspension of small solid particles in the aqueous phase; and separating and drying the solid particles, which are toner particles having a non-spherical shape.
一种通过有限凝聚形成非球形调色剂颗粒的工艺,包括:形成一个有机相,其中包括聚合物材料、
颜料、季
铵四苯
硼酸盐和一种不溶于
水的液体;将有机相分散在含有固体胶体稳定剂的
水相中;通过高剪切搅拌形成有机相在
水相中的小液滴悬浮液;从小液滴中去除不溶于
水的液体,从而形成小固体颗粒在
水相中的悬浮液;分离和干燥固体颗粒,这些颗粒是具有非球形状的调色剂颗粒。
