ABSTRACT:
Disclosed is an electrostatic image output apparatus comprising a layer composed of a dielectric material or a photoconductor, image element electrodes arranged in the form of a matrix on one surface of said layer, field effect transistors affiliated with the image element electrodes and interposed between the image element electrodes and the earth, and a charging mechanism arranged on the other surface of the dielectric material or photoconductor layer.
In this electrostatic image output apparatus, an electrostatic image having a high surface potential and a high potential contrast can be formed by an electric signal of a very small output and therefore, an image excellent in the image quality and density can be obtained without tailing or shadowing.
