A toner includes toner particles containing at least a binder resin and a colorant, and inorganic fine particles. The shape factor SF-1 of the toner particles is in a specific range. The toner has a storage elastic modulus at 140.degree. C., G' (140.degree. C.), in a specific range the toner comes to have a viscosity of 1.0.times.10.sup.3 Pas according to a flow tester heating method at a temperature of from 115.degree. C. or more to less than 130.degree. C.
