The present invention provides a method for making an electrophotographic printing plate by reversal development which comprises uniformly charging the surface of an organic photoreceptor comprising an electrically conductive support and, provided thereon, an organic photoconductive compound bound with a resin binder, exposing the surface to a light image to form a static latent image corresponding to the light image on the surface of the organic photoreceptor and then, subjecting the static latent image to reversal development with an electrophotographic liquid developer containing charged toner particles, characterized in that the reversal development is carried out with the electrophotographic liquid developer having an electrodeposition potential set within the range of 0-80 V in absolute value.
