Abstract:
1. A method of preparing a toner, comprising: preparing a high molecular weight latex particle by polymerizing a toner composition, the toner composition including a macromonomer having a hydrophilic group, a hydrophobic group and at least one reactive functional group, and at least one polymerizable monomer; forming a core particle by aggregating the high molecular weight latex particle, wherein the forming of the high molecular weight latex particle and the aggregating the high molecular latex weight particle are performed without an emulsifier; and forming a shell layer by coating the core particle with a polymer having a higher glass transition temperature than a glass transition temperature of the core particle, wherein the macromonomer is formed of a material selected from the group consisting of polyethylene glycol (PEG)-methacrylate, PEG-ethyl ether methacrylate, PEG-modified urethane, PEG-modified polyester, polyacrylamide (PAM), PEG-hydroxyethyl methacrylate, dendritic polyester acrylate, carboxy polyester acrylate, fatty acid modified epoxy acrylate, and polyester methacrylate.
