Abstract
A liquid ink development (LID) reproduction machine for producing a stabilized liquid toner image having clean-background areas. The reproduction machine includes a movable image bearing member having a photoconductive surface, and latent image forming devices for forming a latent image on the photoconductive surface such that the latent image has image areas and background areas. The reproduction machine also includes a development apparatus containing liquid toner developer material for developing the latent image. The liquid toner developer material includes a carrier liquid having a relatively low conductivity for preventing shorting of image conditioning electric fields through a layer of the liquid toner developer material forming the image. The liquid toner developer material also includes charged toner particles dispersed within the carrier liquid and having a relatively high charge level per toner particle for making the toner particles more sensitive to a low voltage image conditioning electric field. More importantly, the reproduction machine includes an image stabilization roller having a relatively low voltage biasing field for image conditioning so as to achieve effec…
