Abstract
A fluid flow assisted ion projection printing head having an electrically conductive metal body defining an elongated ion generation chamber, a corona wire supported within said chamber for generating ions, an entrance channel in the body for introducing transport fluid to the chamber, an exit channel at least a portion of which is defined by the body for directing transporting fluid with entrained ions from the chamber, and modulation means for neutralizing ions in selected portions of the exiting entraining fluid has substantially all surfaces thereof effected by the extended exposure to the chemistry of the corona discharge coated with a substantially continuous thin conductive film of aluminum hydroxide containing conductive particles. In a preferred embodiment, the conductive metal is aluminum and the conductive particles are graphite particles.
