摘要： A marking apparatus is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. A liquid marking material, such as ink, is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.

摘要： An acoustic scavengeless assist (ASA) development apparatus, and a multicolor image reproduction machine including such a development apparatus. The (ASA) development apparatus includes a biased vibratory section having a piezoelectric member and a donor member, as well as, a development electrode section, for presenting toner particles to latent electrostatic images for image development. The donor member is positioned within the reproduction machine and forms a development nip with a latent image bearing surface of a photoreceptor of the reproduction machine. Importantly, the biased vibratory section has at least a first conductive electrode formed therein adjacent to the piezoelectric member for effecting controlled vibratory toner release from the donor member, and a first bias for biasing the at least first conductive electrode. The development electrode section includes a set of second conductive electrodes and a second bias therefor, and is located between the at least first electrode and the latent image bearing surface, for enhancing toner particle release from the donor member, and powder cloud formation within the development nip for quality image development.

摘要： A scavengeless or non-interactive development system is described for use in image formation such as highlight color imaging. A toned donor roll structure having two sets of interdigitated electrodes physically supported by an insulative support structure is provided. An equal magnitude DC potential is applied to both sets of electrodes while an AC potential is applied to either one or both sets of electrodes. The AC and DC biases are such as to preclude background development without creating fringe DC fields between adjacent electrodes.

摘要： A non-interactive or scavengeless development system for use in color imaging. To control the developability of lines and the degree of interaction between the toner and receiver, an AC voltage is applied between a donor roll and electrodes supported adjacent to the surface of said donor roll to enable efficient detachment of toner from the donor to form a toner cloud. An AC voltage applied between the donor roll assembly and an image receiver serves to position the cloud in close proximity to the image receiver for optimum development of lines and solid areas without scavenging a previously toned image.

摘要： Direct electrostatic printing without the use of an apertured printhead structure is accomplished by supplying mechanical energy in an image-wise manner via AC fringe fields coupled to a toned donor member. The A.C. fringe fields are created using paired electrodes positioned behind the donor member where they can properly function notwithstanding fluctuations in the ambient environment.

摘要： This invention relates to an apparatus for simultaneously charging, exposing, and developing imaging members at low voltages which comprises a semi-transparent deflected flexible imaging member, an electronic imaging source means, a light beam deflector member, a modulator means, a laser means, a sensitizing roll means, containing magnets therein, a development roll means containing magnets therein, a voltage source means for the sensitizing roll means, a voltage source means for the development roll means, a developer supply reservoir containing conductive developer particles therein comprised of insulating toner resin particles and conductive carrier particles, a sensitizing nip situated between the flexible imaging member and the sensitizing roll, a development nip situated between the imaging member and the development roller, the sensitizing roll means and development roll means moving in the same direction of movement as the semi-transparent deflected flexible imaging member, the voltage being generated by the voltage source with the sensitizing nip being of an opposite polarity of the voltage generated by the voltage source for the development roller, wherein an electric field of a predetermined polarity is established between the semi-transparent deflected flexible imaging member and the sensitizing roll means, which field exerts in the sensitizing nip an electrostatic force on the charged toner particles causing these particles to uniformly migrate toward the imaging member, subsequently subjecting the deflected flexible imaging member to the electronic image source whereby the electrostatic force exerted on the toner particles adjacent the light struck areas of the flexible imaging member are increased thereby causing toner particles to be deposited on the deflected flexible imaging member, and wherein toner particles are removed from the deflected flexible imaging member in areas not exposed to light by the development roll and developed in the areas exposed to light.
