Abstract
An electrostatographic imaging apparatus is disclosed. The imaging apparatus includes a photoconductor assembly; means for positioning the inner surface of a dielectric web against the photoconductor whereby an air gap is formed between the photoconductor and the web; charging and exposing means; a conductive roller which is biased at a potential sufficient to prevent charge transfer from the photoconductor to the web; a liquid developing system; and means for transferring the developed image from the web to an image copy member.
Claims4
An electrostatic imaging apparatus comprising:
- a photoconductor assembly;
- means for positioning the inner surface of a dielectric web against said photoconductor whereby an air gap is formed between said photoconductor and said web;
- charging means for applying a charge to the outer surface of said web;
- means for exposing a light pattern through said web, whereby the air gap is ionized and forms a latent image on the inner surface of the web;
- means for guiding the latent image bearing web away from the photoconductor, including a conductive roller, said roller being biased at a potential sufficient to prevent charge transfer from said assembly to said web;
- a liquid developing system for developing the latent image on said web;
- and means for transferring said developed image from said web to an image copy member.
