ABSTRACT:
A system for removing excess carrier liquid from an electrostatic image developed with liquid developing material made up of toner particles immersed in a liquid carrier medium on an image bearing member. The system includes an absorbent contact roller for absorbing at least a portion of the liquid carrier off of the liquid image, a vacuum source coupled to the contact roller for generating negative pressure at the surface of the roller to draw the absorbed liquid through the contact roller, and a nonpermeable vacuum sealing membrane member partially surrounding the contact member in an area not adjacent to the image bearing surface for reducing the surface area of the contact roller which is exposed to the ambient atmosphere to create a vacuum sealing arrangement adapted to deliver negative pressure airflow to a selected area adjacent the image bearing surface.
