Abstract

A digital printing apparatus using liquid toner comprising chargeable imaging particles and carrier liquid, comprising an imaging member (140) to sustain a pattern of electric charge forming a latent image on its surface, a development member (130) to receive toner (100) from a reservoir (110), and to develop the image by transferring toner onto the imaging member (140) in accordance with the pattern, leaving a remaining fraction of the toner on the development member (130), an electrical field generating means to compact the particles by applying a field before transfer onto the imaging member (140), means (150, 160) for depositing the toner onto a substrate (199), and means (133) for removing remaining toner from the development member (130), comprising an integrated source for generating an oscillating electric field, arranged to decompactify the chargeable imaging particles and mechanical removal means for removing the liquid toner.
