The present invention relates to a toner for electrostatic development produced by a suspension process accompanied with reverse-neutralization and the method of producing the toner. The method for producing the toner for use in electrostatic development according to an embodiment includes (a) reacting a linear low molecular weight polymer having carboxyl groups at the end of a polymer chain with a basic compound to convert the polymer into neutral salt form and adding distilled water to prepare a water-dispersible composition to function as a dispersant; (b) mixing the water-dispersible resin composition with a colorant, a charge control agent, a releasing agent and a cross-linked high molecular weight water-dispersible latex to form a colored resin dispersion using high shear force; (c) pouring the colored resin dispersion into an acidic solution while applying a high shear force to reverse neutralize the neutral salt and heating and stabilizing the solution to obtain toner particles; and (d) filtering and washing, two or three times, repeatedly, and vacuum drying the toner particles and mixing the dried toner particles with hydrophobic silica particles or hydrophobic titanium oxide particles in an amount of 1-5 wt %.
