PURPOSE: To make recording effective on the recording paper for low humidity without deteriorating recording density even under high temperature and humidity conditions by applying control voltage with small building-up time constant to control electrodes after applying recording voltage with large building-up time constant to recording electrodes.

CONSTITUTION: A dielectric layer 3 is formed on one side of the conductive base 2 for eledtrostatic recording paper 1 and pressed onto an electrostatic recording head 5 comprising a control electrode 4 and a multitude of recording electrodes to electrostatic recording. Recording voltage Vn is first applied to the recording electrodes and then control voltage Vc is applied to the control electrode 4 late by the time Td. The recording voltage Vn has been already saturated nearly at 90% by that time, and a peak value Vp+Vn prevailing while voltage Vp induced on the control voltage Vc passes a peak value thus increases, thereby improving the recording density. The recording paper for low humidity is made now available for recording even under high temperature and humidity conditions.
