PURPOSE:To avert ghost and to improve image grade by dividing a conductive layer respectively via high-resistance parts to the widths corresponding to the respective stylus electrode groups of a recording head. CONSTITUTION:Electrostatic recording media 21 are provided opposite to the recording heads 2 consisting of the plural electrode groups A, B consisting of the plural writing stylus electrodes 3 which are respectively independently controlled and control electrodes 4 facing the respective electrode groups A, B. The electrostatic recording media 21 are formed by having the conductive layers 23 and the dielectric layers 24 which are opposed to the stylus electrodes 3 and are electrified by the recording heads 2. The conductive layers 23 are constituted by being divided respectively via the high-resistance parts (including insulating parts) 25 to the widths W corresponding to the widths of the respective electrode groups A, B. As a result, the influence of the voltages of the control electrodes 4 selected at the time of writing is shut off by the high- resistance parts 25 and is no longer exerted to the stylus electrode side of the same system connected to the selected stylus electrodes 3. The ghost is thereby averted and the image grade is improved. |
