The process comprises the steps of forming a first electrostatic image by charging a photoconductive layer formed on a first ion beam controlling screen, exposing the charged photoconductive layer imagewise to light based on a first image information, disposing a recording material having an insulating surface so that it confronts the exposed photoconductive layer and radiating ions on the insulating surface of the recording material through said first screen; and forming a corrected electrostatic latent image by charging a photoconductive layer formed on a second ion beam controlling screen, exposing the charged photoconductive layer of the second screen to light based on a second image information, disposing the recording material having the first electrostatic image formed thereon so that it confronts the exposed photoconductive layer of the second screen and radiating ions on the insulating surface of the recording material through said second screen. Each of the first and second ion beam controlling screen comprises a base composed of a metal lattice having numerous penetrating holes, a photoconductive layer formed on one surface of the base, an insulating layer formed on the other surface of the base, and a biasing conductive layer formed on the insulating layer.
