A method for developing an electrostatic latent image comprising, a step of supplying a developer containing a carrier and a toner, said toner consisting of fine toner particles of which not less than 95% by weight have a particle size of from 1/1.7 to 1.7 times as large as the weight average size of the toner particles (D50), to the outer circumfence of a cylinder-shaped sleeve member of a developer transporting means, a step of forming a thin layer of said developer on the surface of said sleeve member by the use of a layer thickness regulating member so that the maximum thickness of the developer layer is smaller than the minimum distance between the surface of said sleeve member and the surface of said electrostatic latent image carrying member, a step of carrying said developer to close proximity of the electrostatic latent image formed on said electrostatic larent image carrying member, and a step of forming a toner image on said electrostatic latent image carrying member is disclosed.
