PURPOSE:To reduce manufacturing cost while keeping performance by a method wherein a layer which is more excellent in anode solubility resistance than a conductive component is provided outside the conductive component in an ink roller. CONSTITUTION:Ink K on an ink roller SR is electrified from a power source BT by utilizing electrical an image forming method with the ink roller being employed as a positive electrode and a plate cylinder as a negative electrode. Then, the ink K is selectively moved to the non-conductive part on a plate composed of a conductive part formed with a copper foil fixed onto the plate cylinder P and a non-conductive part formed by resin or the like, and an ink image is formed on the plate cylinder. Then, the formed ink image, after being transferred to a branket B being an image receiving material opposed to the plate cylinder P by pressurizing, pinches a material to be recorded RP being a final image receiving material jointly with an impression cylinder I to perform recording. In that case, for the ink roller SR, a layer (platinum) 8 which is more excellent in anode solubility resistance than a conductive component (ascicular nickel) 7 is formed outside this conductive component 7. |
