    • A method of preparing a toner, includes: preparing a core by mixing a polyester resin and a colorant with at least one material selected from the group consisting of a macromonomer having hydrophilic group, hydrophobic group, and at least one reactive functional group and a reactive emulsifying agent. A shell is formed on the core by polymerizing the exterior surface of the core with one or more polymerizable monomers and an initiator, wherein at least one material selected from the group consisting of the macromonomer and the reactive emulsifying agent participate in the polymerization reaction. Also, provided are a toner prepared using the method, an image forming method using the toner, and an image forming apparatus employing the toner. According to the method, a polyester resin, having superior fixability at low temperature and image properties, is used as a core composition and styrene, having superior maintenance and charging properties, is used as a shell composition in the process of manufacturing a core/shell structure to prepare the toner for the image forming apparatus having fast speed and fixability of high quality images at low temperature. In addition, by not using the reactive emulsifying agent, the cleaning process is minimized, and the amounts of polluted water and waste water are decreased, which is very advantageous environmentally.
    • 制备调色剂的方法包括:通过将聚酯树脂和着色剂与选自具有亲水基团,疏水基团和至少一个反应性官能团的大分子单体和反应性官能团中的至少一种材料混合来制备核心, 乳化剂。 通过使核心的外表面与一种或多种可聚合单体和引发剂聚合而在核心上形成壳,其中至少一种选自大分子单体和反应性乳化剂的物质参与聚合反应。 此外,提供了使用该方法制备的调色剂,使用该调色剂的图像形成方法以及使用该调色剂的图像形成设备。 根据该方法,将具有优异的低温定影性和图像性质的聚酯树脂用作芯组合物,并且在制造芯/壳的过程中使用具有优异的维持性和带电性的苯乙烯作为壳组合物 结构来制备用于在低温下具有高速图像和高质量图像的定影性的图像形成装置的调色剂。 此外,通过不使用反应性乳化剂,清洁过程被最小化,并且污染水和废水的量减少,这对环境非常有利。
