Abstract
A developing method for developing an electrostatic latent image at a developing region includes preparing a developer containing toner particles and carrier particles which has an inherent resistance value of 1.times.10.sup.7 .about.1.times.10.sup.12 .OMEGA.ocm under an electric field of 500V/mm, magnetic force of 600.about.2300 G, and a mean particle size of 10.about.30 .mu.m; regulating a quantity of the prepared developer on a developer transporter within a range of 0.7.about.5.0 mg/cm.sup.2 ; transporting the regulated developer to the developing region; and applying an alternating current voltage between the developing region and the electrostatic latent image to generate an oscillating electric field therebetween in order to supply the transported developer to the electrostatic latent image.
