ABSTRACT:
An electrostatic recording apparatus comprising an ion modulator, a driving circuit for transforming a first image signal into a second image signal and for applying said second image signal to the ion modulator, a member for forming electrostatic latent image, and a photon coupled isolator. A voltage of the second image signal is higher than a voltage of the first image signal. The first image signal is supplied to the driving circuit through the photon coupled isolator. The ion modulator is a multilayered ion modulator comprising a layer of insulating material, a continuous layer of conductive material and a segmented layer of conductive material on the other side of said insulating layer. Each segment of the segmented conductive layer is insulatively isolated from each other segment. The multilayered ion modulator has at least one of row of apertures formed therethrough. A segment of the segmented conduction layer is formed around each aperture.
