Abstract:

Disclosed are ionographic imaging apparatuses and processes. One apparatus comprises an imaging means, means for applying to the imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, ionographic writing means for generating a latent image on the peel layer, means for developing the latent image on the peel layer, and means for simultaneously transferring the peel layer bearing the developed image from the imaging means to a substrate and affixing the peel layer bearing the developed image to the substrate. In another embodiment, the apparatus employs a process which comprises applying to an imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, forming a first latent image on the peel layer with an ionographic writing means, developing the first latent image with a first developer, forming a second latent image on the peel layer containing the first developed image with an ionographic writing means, developing the second latent image with a second developer, forming a third latent image on the peel layer containing the first and second developed images with an ionographic writing means, developing the third latent image with a third developer, and simultaneously transferring the portion of the peel layer that bears the developed images to a substrate and affixing the peel layer bearing the developed images to the substrate. A further embodiment is directed to an apparatus and process for sequentially forming and developing primary color images on an imaging means to form a full color image, followed by trasnsferring the fully formed image to a substrate, wherein the developers employed contain a release agent.
