Abstract

PURPOSE:To obtain a titled device, wherein a roller is compressed to an electrostatic recording head only during the period recording paper is electrostatically recorded between the electrostatic recording head and the roller, and the electrode of the electrostatic head is not damaged by the rotation of the roller. CONSTITUTION:When the leading edge of the roll shaped recording paper 13 is detected by a detector 20, a solenoid is energized and the roller 22 is approached and displaced to the electrostatic recording head 21. The recording paper is contacted with the surface of the electrostatic head and fed, and a clear electrostatic image is formed. When a detector 52 detects the fact that a motor 40 has fed the recording paper by a specified length, a cutting device 16 cuts the roll shaped recording paper 13. When the rear edge of the cut recording paper is detected by the detector 20, the solenoid is deenergized, and the roller 22 is separated from the electrostatic recording head 21 and lowered.
