ABSTRACT:
Provided a toner including at least: toner particles each containing at least a binder resin, a release agent, and a colorant; and an inorganic fine powder, in which: a degree of aggregation Y1at a time of compression (200 kpa) of the toner satisfies a relationship of 15≦Y1≦35, and a degree of aggregation Y2at a time of non-compression of the toner satisfies a relationship of 7≦Y2≦15; and a highest endothermic peak of the toner is present in a temperature range of 30 to 200° C. in an endothermic curve measured with a differential scanning calorimeter (DSC), and a peak temperature Tsc (° C.) of the highest endothermic peak satisfies a relationship of 60≦Tsc≦130.
