Disclosed is a novel method for application of liquid devel-oper to a photoconductive surface bearing a latent electro-static image. According to this method, a "gravure" roller is formed magnetically utilizing a conventional magnetic brush developer system and preferably spherical carrier particles. The "gravure" roller is formed by selectively applying a field across the roller so as to cause the magnetic particles to adhere to its surface in a uniform pattern. The pattern is preferably essentially the same as that of a conventional gravure roller. Liquid developer may thereafter be doctored on the "gravure" roller in the conventional fashion and trans-ferred to a photoconductive surface bearing a latent electro-static image.
