TONER FOR DEVELOPING ELECTROSTATIC IMAGE AND METHOD FOR PREPARING THE SAME, MEANS FOR SUPPLYING THE SAME, AND IMAGE-FORMING APPARATUS EMPLOYING THE SAME

摘要

PURPOSE: A toner for developing electrostatic images, a method for preparing the same, a toner supplying apparatus using the toner, and an image forming apparatus using the same are provided to improve the image characteristic of toner. CONSTITUTION: A toner for developing electrostatic images includes binder resins, a coloring agent, and a releasing agent. The binder resins include two kinds of binder resins with different weight average molecular weights. The toner has one or more endothermic peaks at secondary rising curve of differential scanning calorimetry measurement by melting the releasing agent. The endothermic peaks have main endothermic peaks in a range about 70-100 degrees Celsius and auxiliary endothermic peaks in the form of a separate peak or shoulder in a range about 60-80 degrees Celsius. A toner supplying apparatus(100) implements operational processes based on the toner.
