Abstract
A toner for developing an electrostatic latent image contains a binder resin, a colorant, a wax, and inorganic fine particles. The toner contains the inorganic fine particles content in the range from 1 to 10% by weight, the temperature at which the complex viscosity η° of the toner in the case of measuring at a frequency of 100 rad/second shows 1000 Pa.s ranges from 125 to 145° C., and the temperature at which the complex viscosity η° of the toner in the case of measuring at a frequency of 100 rad/second shows 100 Pa.s ranges from 180 to 210° C.
