Electrode assembly and image recording apparatus using same

A recording electrode assembly, relatively moveable with respect to recording medium, for depositing onto the recording medium electrically conductive and magnetic toner having been magnetically conveyed, said assembly comprising:

• an array of recording electrodes electrically isolated from each other, said electrodes adapted to be supplied with an electric voltage representing information to be recorded, wherein the array of recording electrodes is adapted to extend transversely with a direction of the relative movement of the recording material;
• a sleeve of non-magnetic material for supporting on its outer surface said array of recording electrodes;
• a conductive member, electrically isolated from said recording electrodes, for providing a surface member upstream of said recording electrodes with respect to a direction of movement of the magnetically conveyed toner;
• and
• magnetic means disposed inside said sleeve.

An image recording apparatus, comprising:

• a recording electrode assembly, capable of being relatively moved with respect to a recording medium, for depositing onto the recording medium electrically conductive and magnetic toner magnetically conveyed, said assembly including an array of recording electrodes electrically isolated from each other, each electrode 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 said array of the recording electrodes;
• a conductive member, electrically isolated from said recording electrodes, for providing a surface member upstream of said recording electrode with respect to a direction of movement of the toner;
• magnetic means disposed across said supporting member from said array of electrodes, for supplying the toner to said array of the electrodes;
• and a recording medium disposed opposed closely to said array of the electrodes.
