ABSTRACT:
A method of preparing a toner includes: preparing a toner composition including a macromonomer having a hydrophilic group, a hydrophobic group and at least one reactive functional group, at least one polymerizable monomer, and a colorant; emulsion-polymerizing the toner composition in a medium; and separating and drying the polymerized toner. A toner is prepared using the method. An image forming method using the toner, and an image forming apparatus using the toner are also provided. According to the method, the size, distribution and configuration of toner particles are easily controlled. In addition, the method does not involve the use of or minimizes the use of a surfactant, and decreases polluted water and waste water, which is very advantageous environmentally.
