    摘要： A toner having both of excellent low-temperature fixability and such high durable developability as to be free from causing any development stripe. The toner is a toner including a toner particle containing a crystalline resin as a binder resin. When a relative permittivity obtained at a time of impedance measurement of the toner under an environment at a temperature of 25° C. and a relative humidity of 50% is represented by εr, a difference Δεr between a relative permittivity εr(0.01 Hz) at a frequency of 0.01 Hz and a relative permittivity εr(383 kHz) at a frequency of 383 kHz satisfies a relationship of 0.21≤{εr(0.01 Hz)−εr(383 kHz)}≤0.48.
