摘要： An apparatus for developing an electrostatic latent image with liquid developing material. The apparatus includes a liquid developing material coating flow applicator for applying a substantially uniform coating of liquid developing material to a moving surface, wherein a housing, situated proximate to the moving surface, includes a fluid transport channel having a relatively narrow-width elongated outlet port for delivering a flow of liquid developing material to the moving surface, and an air flow channel having an elongated inlet aperture located adjacent the moving surface and immediately upstream from said outlet port for applying vacuum pressure to the flow of liquid developing material for varying the profile of the coating flow to provide variation of flow stability as well as thickness. A discussion of the effects of variations in the outlet port geometry, in particular, increasing the dimension between the downstream wall and the surface to be coated, has also been provided. A developing roll situated adjacent to and downstream from the liquid developing material is also provided for attracting the liquid developing material to image areas of the electrostatic latent image.

摘要： A system and method for color mixing management in an electrostatographic printing system, wherein a developing material reservoir containing an operative solution of colored developing material including a mixture of selected color components is continuously replenished with selected differently colored developing material concentrates in a predetermined ratio so as to be capable of producing a customer selectable color image area on an output substrate. The present invention may also be utilized to mix a customer selectable color in situ, either from stored proportions known to compensate for developability differences or from approximate amounts of primary color components initially deposited and mixed in the developing material reservoir with the resultant operative developing material mixture continually developed and replenished with a predetermined ratio of color components until the developing material mixture reaches a steady state color.
