    摘要: An apparatus which develops an electrostatic latent image recorded on a photoconductive member with toner. Fluidized toner is transported from one end of the developer housing to the other end. An electrical bias is applied between the toner mover and the donor roller so as to attract toner to the donor roller. A rotating rod resiliently urged into contact with the donor roller charges and meters the toner on the donor roller. Electrically biased wires in the development zone between the photoconductive member and the donor roller detach toners from the donor roll so as to form a toner powder cloud in the development zone. Detached toner from the toner powder cloud develops the latent image.

    摘要: A process and apparatus for charging insulating toner particles wherein there is provided a charging roll containing a triboelectrically active coating, and weakly charged toner particles are transported into contact with the coating contained on the charging roll, this contact being accomplished in a charging zone situated between the charging roll and the transporting mechanism. As a result of contact between the weakly charged toner particles and the triboelectrically active coating contained on the charging roll there is imparted charges of either a positive or negative polarity to the weakly charged toner particles. The apparatus and process of the present invention are useful, for example, in electrostatographic recording imaging devices.

    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.

    摘要: An apparatus in which a donor roll advances toner to an electrostatic latent image recorded on a photoconductive member. A plurality of electrical conductors are located in grooves in the donor roll. The electrical conductors are spaced from one another and adapted to be electrically biased in the development zone to detach toner from the donor roll so as to form a toner cloud in the development zone. In the development zone, toner is attracted from the toner cloud to the latent image. In this way, the latent image is developed with toner.

    摘要: Three fuser rollers cooperate with a pressure roller to form an extended fusing zone through which a substrate carrying toner images passes with the toner images contacting the fusing belt. Electrical power is applied to the three fuser rolls in such a manner that only the portions of the belt in the fusing zone are heated. The energy is concentrated only in the part of the fusing belt where it is needed for fusing the toner images on the final substrate. Thus, the free extent of the belt or in other words the portion of the belt outside of the fusing zone remains unheated. Toner images are directly formed on or transferred to the unheated portion of the fusing belt. The images carried by the belt are then moved through the fusing zone where the images are simultaneously transferred and fused to a final substrate.
