ABSTRACT:
A recording head for electrostatic recording comprises an electrode substrate formed by bonding together by a bonding agent a pair of substantially planar sub-substrates of an electrical insulating material, each of which is formed on its one surface with a plurality of elongate, equally-spaced and parallel recording electrodes electrically insulated from each other and aligned in a row, so that the electrodes on one of the sub-substrates are located, respectively, opposite to the spaces between adjacent electrodes on the other sub-substrate. In the recording head, the electrode row on each of the sub-substrates has a high degree of linearity, and the dimension in the widthwise direction of the electrode substrate defined by the distance between the electrode row on one of the sub-substrates and that on the other sub-substrate is maintained uniform over the whole longitudinal direction of the electrode substrate. A method of making such a recording head is also disclosed.
