TONER AND MANUFACTURING METHOD THEREOF

摘要

An objective is to provide toner by which high quality images can be stably formed for a long duration. Disclosed is a toner possessing toner particles each containing a binder resin and a colorant, wherein the toner particle has a low surface energy group chemically bonded to the binder resin on a surface of the toner particle. It is preferable that the low surface energy group is an aliphatic hydrocarbon group, and the binder resin is urea-modified polyester. Also disclosed is a method of manufacturing a toner containing toner particles each containing a binder resin and a colorant, comprising the step of chemically reacting a compound possessing a reactive substituent and the aliphatic hydrocarbon group on the toner particle surface to chemically combine the aliphatic hydrocarbon group with the binder resin via the reactive substituent on the toner particle surface.
