    • PURPOSE: A manufacturing method of a toner is provided to provide a toner with high image quality by having excellent antistatic performance and durability. CONSTITUTION: A toner comprises a core part which includes a binder resin, colorant, and wax; and a shell part which surrounds the core part and includes a binder resin and inorganic particle. A manufacturing method of the toner comprises a step of injecting a binder resin dispersion, colorant dispersion, wax dispersion, and coagulant into a reactor and forming a toner core part by increasing temperature of the contents; a step of additionally adding the binder resin dispersion and inorganic particle dispersion into the reactor and forming a shell part which surrounds the core part and includes the binder resin and inorganic particle; and a step of increasing the temperature of the reactor to obtain combined toner particle.
    • 目的:提供调色剂的制造方法,通过具有优异的抗静电性能和耐久性来提供具有高图像质量的调色剂。 构成:调色剂包括包含粘合剂树脂,着色剂和蜡的芯部分; 以及包围芯部并且包括粘合剂树脂和无机颗粒的壳部。 调色剂的制造方法包括将粘合剂树脂分散体,着色剂分散体,蜡分散体和凝结剂注入反应器中并通过增加内容物的温度形成调色剂核心部分的步骤; 将粘合剂树脂分散体和无机颗粒分散体另外添加到反应器中并形成围绕芯部的壳部,并且包含粘合剂树脂和无机颗粒的步骤; 以及提高反应器的温度以获得组合的调色剂颗粒的步骤。

    • PURPOSE: A manufacturing method of a toner is provided to have narrow particle size distribution and to obtain a toner image with high quality. CONSTITUTION: A manufacturing method of a toner comprises: a step of forming a mixed dispersion, homogenates, a first agglutinate, and a second agglutinate; a step of increasing the temperature of the second agglutinate to a second temperature and mixing with a third mixing rate to form an integrated toner particle; a step of forming a dried toner particle by cooling, cleaning, and drying the integrated toner particle; and a step of adding an external additive to form a toner particle.
