摘要： A toner is provided. The toner includes at least two types of polyester resins and a release agent. When the toner is subjected to a dynamic viscoelasticity measurement at a frequency of 6.28 rad/sec to obtain a temperature-dependent curve of loss tangent (tan δ), and the temperature-dependent curve is differentiated one time with temperature, a resulting curve has a maximum value of 0.07 or more and a minimum value of 0.025 or less within a temperature range of from 85° C. to 110° C. When the toner is subjected to a differential scanning calorimetry (DSC), an endothermic amount measured in a first temperature rising in the DSC is 3.5 J/g or less within a temperature range of from 85° C. to 120° C.
