ABSTRACT:
In the electrostatic recording process comprising relatively scanning a recording electrode on an electrostatic recording material which is electrically connected between said recording electrode and a counter electrode, applying a high frequency alternating current or asymmetric alternating recording signal formed by amplifying and modulating an image signal by a high frequency carrier wave between said two electrodes to form an electrostatic image on the electrostatic recording material, developing the so formed electrostatic image with a developer and, if desired, fixing the developed image, when a specific dielectric layer is selected to the kind of the recording signal and the electrostatic image formed on the dielectric layer is developed with an electroconductive powdery developer containing a fine powder of a magnetic material, high quality recorded images free of such problems as blurring, tailing, fogging and Moire can be obtained a high recording efficiency.
