A toner including: a binder resin; a releasing agent; and a colorant, wherein the binder resin contains a crystalline polyester resin and a non-crystalline polyester resin, wherein the releasing agent has an endothermic peak temperature of 60° C. to 80° C. at the second temperature rising in differential scanning calorimetry, and wherein the releasing agent is an ester wax which satisfies the following expressions (1) and (2): 1.1 Pa·s≦̸&eegr;*a≦̸2.0 Pa·s . . . Expression (1) 0.001≦̸&eegr;*b/&eegr;*a≦̸1.00 . . . Expression (2) where in Expressions (1) and (2), &eegr;*a denotes a complex viscosity (Pa·s) determined by measuring a dynamic viscoelasticity of the releasing agent at a measurement frequency of 6.28 rad/s, and &eegr;*b denotes a complex viscosity (Pa·s) determined by measuring a dynamic viscoelasticity of the releasing agent at a measurement frequency of 62.8 rad/s. |
