Abstract

In an ionographic device of the type described in U.S. 4,524,371 to Sheridon et al., image quality defects referred to as blooming and solid area trail edge raggedness are sometimes noted. These problems arise from the effect of the electric field of ions already deposited on the charge retentive surface on ions projected towards the surface in subsequent image production. The trajectory of projected ions is altered, so that the ions do not land in expected positions.
