Ionographic color printer with plural print heads removable toner cartridge and one-time usable polymeric web

摘要

A color printer incorporating the invention hereof includes an ionographic image projection head which employs AC and DC potentials to provide an ion pool from which ions may be projected onto a movable dielectric surface. Plural developer modules are arranged about the dielectric surface, each developer module including an ion imaging head and a color toner module. Each developer module, after ion-beam imaging the movable dielectric surface, develops the charge image on the dielectric surface by bringing it into contact with a single color toner module. A processor controls each ionographic image projection head and each associated toner module to immediately apply the color toner after imaging of the dielectric surface. A transfer station is located downstream from the plural developer modules and enables transfer of the full color toned image from the dielectric surface to a sheet after a single pass of the dielectric surface past the plural developer modules.
