A toner containing a toner particle that contains a binder resin and a crystalline material, wherein, in measurement of powder dynamic viscoelasticity of the toner, when T(A)° C. is taken as an onset temperature for a storage elastic modulus E′ obtained at a ramp rate of 20° C./min, EA′(100) Pa is taken as a storage elastic modulus at 100° C. obtained at a ramp rate of 20° C./min, and T(B)° C. is taken as an onset temperature for a storage elastic modulus E′ obtained at a ramp rate of 5° C./min, T(A)−T(B) is 3.0° C. or less, T(A) is from 45.0° C. to 70.0° C., and EA′(100) is from 4.0×10
