摘要： 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.
