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, and vacuum source coupled to the contact roller for generating both negative pressure at the surface of the roller to draw the absorbed liquid through the contact roller, and positive air pressure for pushing contaminated liquid out of the roller.
