Abstract:
An imaging apparatus comprisinga support member including a support surface for supporting a layer of marking material; a marking material supply apparatus for depositing marking material on the surface of said support member to form a layer of marking material thereon; a charging source for selectively delivering charge species to the layer of marking material in an imagewise manner to form an electrostatic latent image in the layer of marking material, wherein the electrostatic latent image includes image areas of a first charge voltage and nonimage areas of a second charge voltage distinguishable from the first charge voltage; and a separator member for selectively separating portions of the marking material layer in accordance with the latent image in the marking material layer to create a developed image and wherein the marking material is comprised of a liquid developer comprised of a nonpolar liquid, resin, colorant, and a charge acceptance component comprised of a cyclodextrin; and wherein said cyclodextrin captures negative ions or positive ions thereby enabling a negatively charged liquid developer or a positively charged liquid developer, respectively.
