    • PURPOSE: A toner for developing electrostatic image, and a method for preparing the same are provided to include an average molecular weight less than 75,000, thereby maintaining fixing characteristic. CONSTITUTION: A toner for electrostatic image developing comprises latex, a coloring agent and a release agent. In much than 0°C of storage elastic modulus and loss elastic modulus, the lowest cross temperature is about 65-80°C. The toner for electrostatic image developing has weight average molecular volume of about 65,000-75,000 and z- average molecular weight of about 110,000-220,000. Latex particle, pigment distributing solution and release agent distributing solution are mixed. Coagulant is added to mixing solution. A first coherence toner is heated over glass transition temperature of the latex particle. A supply unit(103) is installed at a lower portion of a toner tank(101), and discharges the toner stored in the toner tank.
