When employing liquid toners to develop charged areas of an image receiver, two major problems must be dealt with: (1) removal of background noise which refers to areas of an electroreceptor that were uncharged, but nonetheless '1 ave some weakly attached toner, and (2) removal of excess liquid toner vehicle which may be, for example, ISOPARa. U.S. Patent 5,063,413 to Domoto, et al., describes an air shear to remove excess liquid toner vehicle from an area of an electroreceptor covered with liquid toner. Although the air shear is effective in removing excess vehicle, it does not contribute to the removal of background toner. Therefore, to overcome the aforementioned limitations, a devise is proposed to remove excess liquid toner vehicles as well as the background toners after development with an electrostatic liquid ink developer.
