Abstract

PURPOSE:To enable to obtain parallelism of a recording member with a charged- particle generating source, by supporting control electrodes arranged in the shape of a curved surface or bent around the openings or the positions of displacement thereof in a picture image forming device wherein charged particles are modulated. CONSTITUTION:An ion current from a corona discharger 7, which is made to run toward a recording member 5 by a counter electrode 6, is controlled by a signal voltage from a character generator 8, which is impressed between a signal electrode 1 and a base electrode 3 with an insulating layer 2 interposed between them, and an electrostatic latent image is formed on the recording member 5 by ions thus modulated. Control electrodes each of which is constituted by said signal electrode 1 and base electrode 3 have openings 4 having the diameter of 150mu each and made by eight per 1mm. in zigzag form, and are stuck on a control-electrode supporting body 10 forming a curved surface having the radius R of about 150mm.. By this constitution, uniform parallelism can be obtained throughout the whole surfaces of the recording member and a charged-particle generating source in the longitudinal direction thereof, and in addition, a mechanical strength can be given thereto.
