Abstract
A toner of the present invention includes at least a colorant and a resin, has crystallinity CX or 20 or greater, and has a dynamic viscoelasticity characteristic in which a logarithmic value Log G′(50) of storage elastic modulus (Pa) at 50° C. is from 6.5 to 8.0 and a logarithmic value Log G′(65) of storage elastic modulus (Pa) at 65° C. is from 4.5 to 6.0, when the dynamic viscoelasticity characteristic is measured by temperature sweep from 40° C., at a frequency of 1 Hz, at a strain amount control of 0.1%, and at a temperature elevating rate of 2° C./min.
