The present invention relates to a non-magnetic toner for developing electrostatic latent images, having; an average degree of roundness of not less than 0.960, a standard deviation of degree of roundness of not more than 0.040, a value of D/d50 of not less than 0.40, in which D=6/( rho xS) ( rho is a true density of toner (g/cm3), and S is a BET specific surface area of toner (m2/g)); d50 is an average weight particle size of toner, and an adhesive stress of 6 g/cm2 or less under a compression of 1 kg/cm2. The non-magnetic toner for developing electrostatic latent images provides high-quality images not only in low-speed areas, but also in high-speed areas, and has a superior transferring properties.
