Abstract
A development electrode arrangement located in closely-spaced parallel relation to the charge retaining surface of a moving electrographic recording medium. A toner application unit feeds electrostatically charged toner particles into the space between the development electrode arrangement and the charge retaining surface of the recording medium. The development electrode arrangement is comprised of an array of electrode segments each segment being electrically isolated from each other segment and each segment being allowed to float electrically. The floating electrode segments are so arranged that every element of the recording medium that is subjected to the toning process passes over at least one electrode segment during the toning process.
