ABSTRACT:
In the electric recording process comprising relatively moving a pair of a recording electrode and a counter electrode and an electrostatic recording material electrically connected between said two electrodes, applying an electric recording signal 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 high frequency signal formed by amplifying and modulating an image signal is applied as the electric recording signal and the electrostatic image formed on the electrostatic recording material is developed with an electroconductive powdery developer containing a fine powder of a magnetic material, high quality recorded images free of such troubles as blurring, tailing, fogging and Moire can be obtained even at high recording speeds.
