ABSTRACT:
Apparatus for wet-developing an electrostatic latent image comprising an electroconductive, ink supply member having an uneven surface comprising a plurality of raised portions and depressions below the raised portions, at least the surface of the ink supply member being electroconductive; means for supplying ink to the ink supply member so that the ink is held in the depressions; an electrophotographic member bearing the electrostatic latent image; and elastic, electroconductive support member for the electrophotographic member; and means for bringing the ink supply member and the electrophotographic member into substantial contact with one another so that the ink is attracted to the electrostatic latent image to thereby develop the image while minimizing damage to the electrophotographic member because of the elasticity of said elastic support member.
