PURPOSE:To obtain a good picture by installing pin electrode and counter electrodes in 1:1 correspondence. CONSTITUTION:Pin electrodes 5 and their driving circuit 10, and a group of counter electrodes 3' and their controlling circuit 9 are provided with the counter electrodes and pin electrodes in 1:1 correspondence. Voltage is applied to the pin electrodes 5 and the counter electrodes 3 according to an image signal to form a toner image on a recording body 6. As the pin electrodes 5 correspond to the counter electrodes in 1:1, the magnetic field goes straight by application of voltage. Thus, by concentration of magnetic field, recorded picture becomes clear and a good picture can be obtained. |
