PURPOSE:To enhance recording velocity in an electrostatic recording method utilizing ion current modulation, by dividing an ion current modulation electrode into plural blocks, retaining image signals in each given unit corresponding to the blocks, and successively applying them as parallel signals to each block. CONSTITUTION:Image signals converted with CCD5 are applied to an ion current modulation electrode 9 through a processing circuit 7. An ion current emitted from an ion generator 11 is modulated with a modulator 9 and a latent image is formed on a rotary drum 12. This ion current modulation is slow in recording velocity. Therefore, the electrode 9 is divided into 9b1, 9b2-9bm, 9a2-9am. The image signals are converted into parallel signals via a shift register 20 and a latch circuit 21, and they are applied to the electrodes divided into blocks, thus permitting the recording velocity to be made high. |
