摘要： The aggregated particles are manufactured through a method of manufacturing aggregated particles, which includes an aggregating step, a depressurizing step, and a cooling step. In the aggregating step, a slurry is prepared which contains aggregated particles obtained by flowing an aqueous slurry of resin fine particles having a volume average particle diameter in the range of 0.4 μm to 3 μm through a coiled piping in a heated and pressurized state and thereby aggregating the resin fine particles. In the depressurizing step, the slurry containing the aggregated particles is depressurized, and a particle size control is conducted by disintegrating coarse particles so as to homogenize particle diameters of the aggregated particles. In the cooling step, the slurry containing the aggregated particles of which particle diameters have been homogenized is cooled.

摘要： A method for manufacturing a developing agent comprising dissolving a binder resin component in a supercritical fluid or a subcritical fluid, mixing it with a colorant component, reducing the solubility of the binder resin component in the supercritical fluid or subcritical fluid, and causing the binder resin component to be deposited in the form of particles while the colorant component is dispersed within the binder resin component. After the pressure within a reaction vessel is decreased from A (MPa) to B (MPa) (where A>B>critical pressure) following the manufacture of a developing agent, the method proceeds back to a developing agent manufacturing step again when at least a developing agent material and a supercritical fluid or a subcritical fluid are injected into the reaction vessel under high pressure. The method allows the dispersibility of the colorant component in the developing agent to be increased up to a primary particle level, whereby a developing agent with an even particle shape and a narrow particle size distribution can be obtained. The method also makes continuous production possible without the need to open and close the reaction vessel, leading to a high production efficiency.
摘要翻译：一种制造显影剂的方法，包括将粘合剂树脂组分溶解在超临界流体或亚临界流体中，将其与着色剂组分混合，降低粘合剂树脂组分在超临界流体或亚临界流体中的溶解度，并使粘合剂树脂组分以颗粒的形式沉积，而着色剂组分分散在粘合剂树脂组分中。在制造显影剂之后，在反应容器中的压力从A（MPa）降低到B（MPa）（其中A> B>临界压力）之后，该方法至少再次返回到显影剂制造步骤将显影剂材料和超临界流体或亚临界流体在高压下注入反应容器中。该方法允许着色剂组分在显影剂中的分散性增加到初级颗粒水平，由此可以获得具有均匀颗粒形状和窄粒度分布的显影剂。该方法也使连续生产成为可能，而不需要打开和关闭反应容器，从而导致高生产效率。
