    摘要: A method of preparing toner, the method including: preparing latex particles for a core which contain wax by polymerizing a toner composition comprising at least one polymerizable monomer and a macromonomer having a hydrophilic group, a hydrophobic group, and at least one reactive functional group; mixing the latex particles for a core with a self-dispersable pigment dispersion and adding an inorganic salt thereto to prepare a primarily agglomerated toner; and coating latex particles for a shell layer on the primarily agglomerated toner. In addition, a toner prepared using the preparation method, a method of forming image using the toner, and an image forming apparatus using the toner. Accordingly, pigments can be uniformly dispersed even without using an emulsifying agent and a dispersant, and thus images that are uniformly transferred can be obtained, and toner with long-term storage and excellent durability can be prepared.
