ABSTRACT:
A charge electrode assembly useful in an ink jet printer comprises a nonconductive supporting structure in which a multiplicity of grooves are formed. Each groove has a conductive layer of a corrosion-resistant noble metal, preferably platinum or rhodium, thereby forming an electrode. An electric power supply is coupled to the electrodes and energizes selected ones of the electrodes when propelled ink droplets traverse the electrode area.
