    • A toner to develop an electrostatic charge image, the toner including at least a binder resin, a colorant, and a releasing agent, wherein a weight average molecular weight of the toner measured by using a gel permeation chromatography (GPC) method on a tetrahydrofuran (THF) soluble fraction is in a range of about 30,000 to about 80,000 g/mol, wherein a molecular weight distribution curve of the toner obtained by using the GPC method on the THF soluble fraction has at least one peak in a molecular weight range of 100 to 1,000 g/mol, a peak in a molecular weight range of 1,000 to 5,000 g/mol, and a main peak in a molecular weight range of 5,000 to 20,000 g/mol, a method of preparing the toner, a device to supply the toner, and an apparatus and method of forming an image by using the toner. The toner has more than certain levels of low-temperature fixability, an anti-hot-offset property, a charging ability, a gloss property, and a heat storage ability. The toner has a long lifetime, and thus, provides a high-quality image in a stable and energy-saving manner.
    • 用于显影静电荷图像的调色剂,所述调色剂至少包含粘合剂树脂,着色剂和脱模剂,其中通过使用凝胶渗透色谱法(GPC)方法测量的调色剂在四氢呋喃上的重均分子量( THF)可溶性部分在约30,000至约80,000g / mol的范围内,其中通过使用GPC方法获得的调色剂在THF可溶部分上的分子量分布曲线在分子量范围内具有至少一个峰 至1,000g / mol,分子量范围为1,000至5,000g / mol的峰,分子量范围为5,000至20,000g / mol的主峰,调色剂的制备方法, 调色剂,以及通过使用调色剂形成图像的装置和方法。 调色剂具有一定程度的低温定影性,耐热粘合性,充电能力,光泽特性和储热能力。 调色剂寿命长,因此以稳定且节能的方式提供高质量的图像。
