Abstract

An apparatus in which a plurality of liquid images are transferred from a photoconductive member to a copy sheet. The liquid images, which include a liquid carrier having toner particles dispersed therein, are attached from the photoconductive member to an intermediate belt by a biased transfer roll. At the same time, the biased transfer roll squeegees the liquid carrier from the intermediate belt and the toner particles are compacted thereon in image configuration. Thereafter, the toner particles are transferred from the intermediate belt to the copy sheet in image configuration with the use of another biased transfer roll. A vacuum source and an infrared heater is employed to remove residual solvent from the intermediate member left after photoconductor to intermediate member transfer takes place.

Dependent claims

An apparatus for transferring a liquid image having at least liquid carrier with toner particles dispersed therein from a member to a copy sheet, including:

an intermediate member positioned to have at least a portion thereof contacting the member in a transfer zone;
first biased roll transfer means positioned adjacent to a nip formed between the member and said intermediate member for attracting the liquid image from the member to said intermediate member and for roller squeezing the member and said intermediate member with a pressure such that (a) non-imaged areas of the member and said intermediate member are squeezed free of carrier fluid and (b) said intermediate member is deformed by the toner in image areas allowing toner particles and carrier fluid to pass through said nip;
and
means for transferring the toner particles from said intermediate member to the copy sheet in image configuration.
