<p>Apparatus for charging a substrate comprising a dielectric substrate (4), a support member (17) having a first end (23) and a second end (24) between which said member extends substantially parallel to said substrate, a row of electrodes (18) distributed over the support member between the first and second ends, said electrodes extending from the support member in the direction of the substrate, the electrodes having a free end (25) for spraying charge on the substrate, each free end having a mainly substantially fixed distance from the substrate, wherein the said distance in the case of a first electrode (d1) differs substantially from the said distance in the case of a second electrode (d2). <IMAGE></p> |
