US Patent 11181846 Toner

A toner including a toner particle including a binder resin and a crystalline material, wherein in powder dynamic viscoelasticity measurement of the toner, where an onset temperature of a storage elastic modulus E′ obtained when a temperature is raised at 20° C./min is denoted by T(A)° C., and an onset temperature of a storage elastic modulus E′ obtained when a temperature is raised at 5° C./min is denoted by T(B)° C., T(A)−T(B) is 3.0° C. or less, in DSC of the toner, a peak temperature of a maximum endothermic peak is from 50.0° C. to 90.0° C., and an amount of a tetrahydrofuran-insoluble component in the binder resin is from 15% by mass to 60% by mass.
