TONER FOR DEVELOPING ELECTROSTATIC IMAGE AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: A toner for developing an electrostatic image and a method for manufacturing the same are provided to implement an excellent image property and to improve durability. CONSTITUTION: A toner for developing an electrostatic image contains a crystalline polyester resin, non-crystalline polyester resin, a release agent, and a coloring agent. The particle of the toner satisfies equation (1) -4.3 <= log(Sstain / Stoner) <= -2.1 and equation (2) 5 <= Nstain <= 25 wherein Stoner indicates the surface area of the particle and Nstain indicates the number of colored areas.
