TONER

A toner including a toner particle containing a binder resin, wherein the binder resin contains a crystalline resin, and in viscoelasticity measurement of the toner with Tp being a peak temperature of an endothermic peak derived from the crystalline resin in DSC of the toner, given G′(Tp−5, 0.01 Hz)...

Summary:A toner including a toner particle containing a binder resin, wherein the binder resin contains a crystalline resin, and in viscoelasticity measurement of the toner with Tp being a peak temperature of an endothermic peak derived from the crystalline resin in DSC of the toner, given G′(Tp−5, 0.01 Hz) as a storage modulus at a temperature of Tp−5° C. and a frequency of 0.01 Hz, G′(Tp−5, 10 Hz) as a storage modulus at a temperature of Tp−5° C. and a frequency of 10 Hz, and G′(Tp−30, 10 Hz) as a storage modulus at a temperature of Tp−30° C. and a frequency of 10 Hz, the following formulae are satisfied:G′(Tp−30,10 Hz)/G′(Tp−5,0.01 Hz)≤1.40G′(Tp−5,10 Hz)/G′(Tp−5,0.01 Hz)≤2.20.
