An electrostatic image forming apparatus in which computer generated image information is converted into a pattern of electrostatic fields, includes a particle source including a particle carrier (33) which holds a layer of electrically charged particles that are transported toward a back electrode via apertures in a printhead structure or structures (202-205). The particles are received on an image receiving member (201) to form an image. The image is formed by passing the image receiving member more than once past each printhead structure so that part of the image is formed on each pass. The printhead structures and/or image receiving member being moved relative to each other such that adjacent columns of print are not printed by the same aperture in different passes. |
