    Abstract: A method of preparing a toner, including: preparing a colorant dispersion by mixing a reactive emulsifier and a colorant; preparing a toner composition by mixing a macromonomer including a hydrophilic group, a hydrophobic group and at least one reactive functional group, at least one polymerizable monomer and a chain transfer agent with the colorant dispersion; emulsion polymerizing the toner composition in a medium; and separating and drying the polymerized toner, wherein the amounts of the macromonomer and the chain transfer agent are controlled to regulate the configuration of toner particles. A toner prepared using the method, an image forming method using the toner, and an image forming apparatus using the toner are also provided by the invention. According to the method, the size and configuration of toner particles are easily controlled. In addition, the method minimizes the use of a surfactant, and decreases polluted water and waste water, which is very advantageous environmentally.

    Abstract: The present invention is a method for the preparation of electrostatographic toner that includes the following steps. A polymer material is dissolved in an organic solvent to form an organic phase that includes a metal complex of zinc dimethyldithiocarbamate; zinc diethyldithiocarbamate; dibenzyldithiocarbamate, zinc di-n-butyldithiocarbamate. The organic phase is dispersed in an aqueous phase that includes a particulate stabilizer to form a dispersion and the resultant dispersion is homogenized. The organic solvent is evaporated and the resultant product is recovered, washed and dried.
