TONER FOR DEVELOPING ELECTROSTATIC IMAGES AND A METHOD FOR MANUFACTURING THE SAME CAPABLE OF SATISFYING THE HIGH GLOSSINESS AND THE HIGH TEMPERATURE STORAGE CHARACTERISTIC BY STRICTLY CONTROLLING THE COMPATIBILITY OF TONER MATERIALS

摘要

PURPOSE: A toner for developing electrostatic images and a method for manufacturing the same are provided to stably form images with the high quality and improve the electrification stability, the low temperature fusing characteristic, and the durability. ;CONSTITUTION: A toner for developing electrostatic images includes a core layer and a shell layer. The core layer includes a first binder resin, a coloring agent, and a releasing agent. The shell layer includes a second binder resin. The first binder resin includes an amorphous polyester resin and a crystalline polyester resin. The second binder resin includes non-crystalline polyester resin. The melt temperature of the crystalline polyester resin represents Tm(C), the melt temperature of the releasing agent represents Tm(W), and the melt temperature of the toner represents Tm(T). The value of Tm(W)-Tm(C) is between -20 and 20 degrees Celsius. The value of Tm(C)-Tm(T) is between 0 and 10 degrees Celsius. The toner is supplied through a toner supplying unit(100).;COPYRIGHT KIPO 2011
