An advantage of ionography over xerography is its elimination of the need for a photoreceptor. In its place, a non light sensitive dielectric receptor of appropriate dielectric constant and thickness is used to retain a latent electrostatic image formed by controlled ion deposition onto its surface. Non light sensitive dielectric receptors, however, force an erase function to depend upon contact (typically via corona) with the top surface of the receptor. Internal polarization and/or trapped charge may result in failure of the erase function due to dielectric relaxation effects. This problem has been encountered in printers manifesting itself in the form of ghost image artifacts in prints.
