摘要： Provided is toner particles comprising a binder resin and a colorant, wherein the binder resin includes a polyester resin having a weight average molecular weight of about 6,000 to about 100,000, a glass transition temperature of about 55 to about 70 o C, and polydispersity index (Mw/Mn) of about 3 to about 25, and the toner particles have a volume average diameter of about 2 to about 10 µm and a 80% span value of 0.9 or less. Unlike conventional toner that has a poor fixing property, the toner particles have a small volume average diameter, a narrow particle size distribution, improved fixing property, and improved high temperature storage stability even though the polyester resin is used as the binder resin.

摘要： Provided is a method of preparing a toner, the method including: preparing a solvent emulsion by stirring a medium including a polar medium, an organic solvent, and a surfactant; adding toner components including a resin and a pigment to the solvent emulsion; removing the organic solvent from the solvent emulsion including the toner components; and collecting a toner particle from the solvent emulsion from which the organic solvent is removed. Unlike a conventional method of preparing a toner, wherein toner components are first dissolved in an organic solvent and then dispersed in an aqueous phase, the method prepares toner particles by forming a solvent emulsion and then adding toner components in the solvent emulsion and dissolving the toner components in the organic solvent dispersed in the solvent emulsion. By controlling an order of adding the toner components, it is easy to control a structure of the toner. Accordingly, a toner having a small volume average particle size, a narrow particle size distribution, an improved fixing property, and an improved storage stability at a high temperature is prepared. Also, it is easy to adjust toner surface charges by selectively using the pigment in a form of a master batch and encapsulating the pigment.
摘要翻译：提供一种调色剂的制备方法，该方法包括：通过搅拌包含极性介质，有机溶剂和表面活性剂的介质来制备溶剂乳液; 向所述溶剂乳液中添加包括树脂和颜料的调色剂组分; 从包括调色剂组分的溶剂乳液中除去有机溶剂; 并从除去有机溶剂的溶剂乳液中收集调色剂颗粒。不同于调色剂的常规方法，其中调色剂组分首先溶解在有机溶剂中然后分散在水相中，该方法通过形成溶剂乳液制备调色剂颗粒，然后在调色剂中加入调色剂组分并溶解调色剂分散在溶剂乳液中的有机溶剂中的组分。通过控制添加调色剂组分的顺序，容易控制调色剂的结构。因此，制备了具有体积平均粒径小，粒径分布窄，定影性能好，高温储存稳定性好的调色剂。此外，通过选择性地使用母料形式的颜料并包封颜料，容易调节调色剂表面电荷。
