Abstract
Image recording method of the present invention comprises the steps of forming electrostatic latent image on a latent image carrier by a latent image forming means, developing the formed electrostatic latent image with toner, and transferring the visualized toner image to a transfer material after repeating at least the developing step plural times, wherein double-element developer formed from mixing toner and magnetic carrier with its density of 4.0 g/cm.sup.3 or less is used in at least the second and the succeeding developing steps among the plural times of the developing steps.
