Abstract
A method of preparing a toner, includes: preparing a high molecular weight latex particle by polymerizing a 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; forming a shell layer by coating the core particle using a polymer having a higher glass transition temperature than a glass transition temperature of the core particle. Also, provided are a toner prepared using the method, an image forming method using the toner, and an image forming apparatus using the toner. Using the toner, an image can be fused at a low temperature. Also, durability of the toner is improved.
