Abstract
A flexible printed circuit (1) has conductive tracks (2) each having one end constituting an electrode in a linear arrangement of electrodes. The back of the printed circuit in the vicinity of said arrangement of electrodes is pressed against a convex structure and an insulating film (3) covers printed circuit away from the electrodes in order to ensure a desired gap between the electrodes and the surface of a recording medium (11) pressed against the head. The head is particularly applicable to forming an electrostatic latent image which is subsequently transferred to some other recording medium.
