Abstract
A method of preparing a toner includes: preparing high molecular weight latex particles by polymerizing 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, a colorant and wax; aggregating the high molecular latex particles in the absence of an emulsifier, a colorant, and wax; and separating and drying the aggregated high molecular weight latex particles. A toner is prepared using the method described above. An image forming method using the toner and an image forming apparatus employing the toner are also provided. Using the method described above, polymerizable toner particles can be prepared using a simplified process and the colorant and was inside the toner can be easily dispersed.
