Electrostatic recording apparatus

摘要

An electrostatic recording apparatus for recording an image represented by a series of binary signals delivered by an image signal source on a recording medium which is moved relative to the apparatus comprises a recording head including a multiplicity of thin strip-shaped recording electrodes having end surfaces substantially aligned on a line substantially perpendicular to a direction of the relative movement of the recording medium, each of the end surfaces having a thickness measured in a direction substantially perpendicular to the line which is smaller than its width measured in a direction parallel to the line, and image signal applying device for sequentially applying a series of binary signals delivered by the image signal source and representative of the image, to the multiplicity of recording electrodes to form the image on the recording medium by dots produced thereon corresponding to the binary signal in such a manner that each of the binary signals is applied equally at a plurality of times to one of the recording electrodes while moving the recording medium relative to the recording head thereby forming one dot corresponding to that binary signal.
