Patent ID: 7585608

Claim:
A method of preparing a toner comprising: preparing high molecular weight latex particles by polymerizing a toner composition comprising a macromonomer having a hydrophilic group, a hydrophobic group and at least one reactive functional group, a colorant, a wax and at least one polymerizable monomer to form the high molecular weight latex particles; aggregating the high molecular weight latex particles in the absence of an emulsifier, a colorant, and wax to form the toner particles; and separating and drying the toner particles obtained from the aggregated high molecular weight latex particles, wherein the step of aggregating the high molecular weight latex particles comprises regulating a pH to control the speed of aggregation, wherein the macromonomer is selected from the group consisting of polyethylene glycol methacrylate, polyethylene glycol ethyl ether methacrylate, polyethylene glycol dimethacrylate, polyethylene glycol reforming urethane, polyethylene glycol reforming polyester, polyacrylamide, polyethylene glycol hydroxyethyl methacrylate, hexafunctional polyester acrylate, dendritic polyester acrylate, carboxy polyester acrylate, fatty acid reforming epoxy acrylate and polyester methacrylate.
