Abstract
Liquid toner imaging apparatus including an image bearing surface, apparatus for developing an image on the image bearing surface using a liquid toner including carrier liquid and pigmented particles, and apparatus for transferring a developed image from the image bearing surface to a substrate. The apparatus for developing includes a developer electrode having a developer surface portions of which sequentially come into propinquity with the image bearing surface and subsequently leave propinquity therewith, each region forming a development region during its propinquity and a stationary nozzle for providing liquid toner of a given color to the development region by supplying liquid toner onto a portion of the developer electrode, wherein the nozzle is spaced more than 8.4 mm from any other nozzle which supplies liquid toner of the given color to the development region.
