The present invention relates to a polymerized toner prepared by suspension polymerization. Provided is a method for preparing a toner comprising the steps of (1) preparing a toner by suspension polymerization using a water-based dispersant that adjusts size of emulsion particles, which are formed as byproduct, to 0.05-2 mum; and (2) removing the dispersant from the toner surface, refining the toner, so that concentration of the emulsion particles becomes 0.01-2 wt % of the toner, and filtering and drying the toner in vacuum. Also provided is a toner prepared by suspension polymerization using a water-based dispersant, concentration of emulsion particles being 0.01-2% and diameter of the emulsion particles being 0.05-2 mum. The present invention provides a good toner having fusing property and developing property by effectively controlling the concentration of emulsion particles formed during suspension polymerization as byproduct.
