摘要:
An apparatus for developing an electrostatic latent image in a liquid developing material-based electrostatographic printing machine including a control system for controlling an amount of marking particles, carrier liquid and/or charge director added to a supply of liquid developing material utilized for developing a latent electrostatic image such that the concentration of marking particles and or charge director can be maintained at an optimal value. The amount of marking particles, carrier liquid and/or charge director in a supply of liquid developing material is maintained at a predetermined optimal value in response to the amount of marking particles and/or charge director depleted from the supply of liquid developing material with each development cycle. A supply reservoir is maintained with a substantially constant amount of liquid carrier to which is added marking particles and/or charge director to provide an operative solution of liquid developing material. For each development cycle, the amount of marking particles and/or charge director depleted from the supply of liquid developing material is determined as a function of the number of picture elements or pixels making up the image being developed. Marking particles and/or charge director concentrate are added to the supply reservoir to maintain the amount of marking particles and/or charge director in the operative solution of liquid developing material at a predetermined value by effectively supplying the marking particles and/or charge director lost by the transport of liquid developing material to the copy substrate.
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.
摘要:
A liquid composition for developing latent electrostatic images comprising toner particles associated with a pigment dispersed in a nonpolar liquid. The salient feature of the invention is that the toner particles are formed with a plurality of fibers of tendrils from a thermoplastic polymer and carry a charge of a polarity opposite to the polarity of the latent electrostatic image. The polymer is insoluble or insolvatable in the dispersant liquid at room temperature. The toner particles are formed by plasticizing the polymer and pigment at elevated temperature and then either permitting a sponge to form and wet-grinding pieces of the sponge or diluting the plasticized polymer-pigment while cooling and constantly stirring to prevent the forming of a sponge while cooling. When cool, the diluted composition will have a concentration of toner particles formed with a plurality of fibers.
