Abstract: A method of forming toner particles includes aggregating a mixture of a latex, a wax, and an optional pigment to form pre-toner particles, and coalescing the pre-toner particles at a substantially constant target temperature selected within a range from about the glass transition temperature of the pre-toner particles to about 75° C., thereby creating toner particles having a substantially constant particle size distribution during the coalescing step.
Abstract translation: 形成调色剂颗粒的方法包括将胶乳，蜡和任选颜料的混合物聚集以形成预调色剂颗粒，并将预调色剂颗粒聚集在基本上恒定的目标温度下，所述目标温度在约玻璃化转变 预调色剂颗粒的温度至约75℃，从而在聚结步骤期间产生具有基本恒定的粒度分布的调色剂颗粒。
