Abstract
PURPOSE:To achieve the simplification of a switching circuit by grounding at least one of two sheets of conductive electrodes which control the ion passage in a small hole and electrically opening the other and forming an electric field in the small hole. CONSTITUTION:An electrostatic recording medium 40 which has been destaticized by a destaticizer 41 and is freshly back-surface-charged by a charger 42 is charged by the corona ion current from a corona ion current generator 47 having passed through the small hole of a control electrode 45 provided with a small hole. When the control electrode 45 is grounded or opened by a switching circuit 48, an electric field is formed in the small hole. The electrostatic latent images created by dot patterns by the small hole are developed by a developing device 49.
