A recording electrode assembly which is relatively moved with respect to a recording medium, for depositing onto the recording medium electrically conductive and magnetic toner magnetically conveyed, the assembly includes an array of recording electrodes, electrically isolated from each other, adapted to be supplied with an electric voltage representing information to be recorded, wherein the array is adapted to extend transversely with a direction of the relative movement of the recording material; a supporting member for supporting the array of the recording electrodes; and a conductive member, electrically isolated from the recording electrodes, for providing a surface member at an upstream of the recording electrodes with respect to a direction of movement of the toner magnetically conveyed.
