摘要：
In an ionographic device projecting a stream of ions towards a moving imaging surface, modulated in imagewise fashion, one or more control electrodes may be arranged adjacent to the path of the ion stream and between the source of the modulated ion stream and the imaging surface, biased with a voltage preventing previously deposited charge from perturbing the trajectory of subsequently projected ions to limit the amount of ion beam deflection caused by the presence of electrostatic charge patterns on the electroreceptor.
