摘要： PROBLEM TO BE SOLVED: To provide toner which has an excellent low-temperature fixability, an excellent offset resistance, and a heat-resistant storage property, and does not contaminate a fixing device and an image, and a manufacturing method of the toner.SOLUTION: The toner is used for developing an electrostatic image and includes toner base particles containing at least a binder resin and a coloring agent. The toner base particles are formed by adding a toner material liquid, which is obtained by dissolving or dispersing a toner material containing the binder resin and the coloring agent in an organic solvent, to an aqueous medium, and granulating it. The toner base particles have a volume average size of 3 to 10 μm. The binder resin contains a polyester resin having a glass-transition temperature of 18 to 40°C, a weight average molecular weight of 10000 to 100000, and a 1/2-method flow start temperature of 70 to 120°C.

摘要： The present invention relates to a toner composition with a broad fusing temperature range and a process for preparing the same. The toner composition according to the present invention creates entanglement between adjacent polymer chains using a nonlinear polyester resin having a branch structure, provides elasticity to molten materials by the branch structure when the resin is molten, prevents the molten materials from being transferred to the surface of a roller at a high temperature, and thereby increases the maximum fusing temperature. Therefore, as the average branch number per polyester resin increases, the maximum fusing temperature rises and the fusing temperature range of the toner composition can be widened.
