Abstract
Imaging apparatus having an image forming surface arranged for movement in a first direction and an image forming apparatus for forming electrostatic latent image and background areas at respective first and second electrical potentials on the image forming surface, a development apparatus biased to a third potential intermediate the first and second potentials for developing the electrostatic latent image using a liquid developer including electrically charged toner particles to form a developed image, the development apparatus having a development surface maintained in a spaced apart relationship from the image forming surface and moving in a direction opposite to the first direction, a background toner removal surface spaced from the image forming surface for the removal of toner particles from the background areas and preferably moving in a direction opposite to the first direction, and an apparatus for supplying a liquid to at least a portion of the space between the image forming surface and the additional surface.
