A nonmagnetic toner which comprises toner particles comprising a binder resin, a colorant, and a wax ingredient and an inorganic fine powder, characterized in that 1) when a temperature at which the value of loss tangent (tanδ), which is the ratio between the storage elastic modulus (G') and loss elastic modulus (G'') of the toner, is maximum in the temperature range of 50-80°C is expressed by T1, then the value of storage elastic modulus of the toner at the temperature (T1), G'(T1), satisfies the relationship 5.00 × 10<=G'(T1)<=1.00 × 10(dN/m), 2) in the temperature range of 50-80°C, the value of loss tangent (tanδ), which is the ratio between the storage elastic modulus (G') and loss elastic modulus (G'') of the toner, is in the range of 0.80-2.00 at the consecutive temperatures in a range which is not narrower than 15°C, and 3) in the temperature range of 120-160°C, the value of loss tangent (tanδ), which is the ratio between the storage elastic modulus (G') and loss elastic modulus (G'') of the toner, is 1.00 or higher.
