After uniformly charging one insulator side of an insulator mesh the other side of which is subjected to electroconductive treatment, the ion flow controlled by recording signals is irradiated for a short period of time on the insulator mesh to obtain a charge distribution wherein the charge on the insulator side is neutralized corresponding to the dots to be recorded. Via mesh apertures which have been freed from the charge by neutralization, the ion flow is irradiated for a time far longer than the above-said short time on an insulating recording substrate, to obtain thereon an electrostatic latent image having an amplified charge distribution.
