摘要： A toner is provided. The toner comprises a binder resin, a release agent, and a function imparting agent comprising a fatty acid amide having a melting point of from 110 to 160 degrees C. When the toner is heated by a differential scanning calorimeter, the toner exhibits no endothermic peak within a temperature range of ±20 degrees C. of a temperature at a highest endothermic peak derived from the fatty acid amide.
