An electrode array forms a latent image by generating an electrical breakdown region and extracting an imagewise distribution of charge carriers which are accelerated toward a separate surface. Different control mechanisms, environments and ranges of operating parameters provide controlled amounts of charge delivered by electrons or ions for improved latent image production. High speed, high resolution and high uniformity of charge deposition are accomplished by different structures within the scope of the invention.

A method of printing with an ionographic printer of the type wherein an array of electrode structures are provided opposite a dielectric member, each electrode structure of the array including a first electrode set for generating a charge breakdown region and a second electrode set for extracting charge carriers from said charge breakdown region and depositing charge on the dielectric member, wherein said second electrode set is maintained at a negative potentional with respect to said dielectric member, and said array is operated to inhibit ions so that electrons deposit said charge on the dielectric member.
