摘要： This invention is generally directed to an improved process for rapidly charging uncharged replenishment toner particles to a positive polarity, and the use of such particles for developing images in an electrostatographic imaging system, which process comprises (1) adding uncharged replenishment toner particles to a charged developer composition comprised of carrier particles and toner particles, the carrier particles consisting of a core containing a polymer coating thereon having incorporated therein an additive having a pKa of less than 5, said additive being selected from the group consisting of perfluorooctanoic acid, 2,4-dinitrophenol, 2,4,6-trinitrophenol, and naphthalene sulfonic acids, (2) contacting the charged developing composition containing said carrier particles with the uncharged toner particles, wherein positive charges are transferred to the uncharged toner particles within a mixing period of from about 5 seconds to about 5 minutes, thereby resulting in substantially the same level of positive charge intensity for said uncharged toner particles as the charge intensity of toner particles in the charged developer composition, said charge intensity ranging from about 0.1 femtocoulombs per micron, to about 3 femtocoulombs per micron of toner particles.

An important embodiment of the present invention is directed to a process for rapidly charging (or admixing) uncharged dry electrostatographic toner, containing the alkyl pyridinium compounds of the above formulas, subsequent to its addition to previously charged developer, whereby the uncharged toner particles acquire a charge within a period of from about 1 minute to about 5 minutes. The toners of this invention are useful for developing images of high quality in an electrostatographic imaging system.

摘要： A printing machine having an operator removable housing comprising a photoconductive member with a web entrained about a portion thereof. A latent image is recorded on the photoconductive member and marking particles transported to the portion of the web entrained about the photoconductive member. In this way, the latent image recorded on the photoconductive member attracts the marking particles to the web in image configuration. A copy sheet is advanced into contact with the marking particles on the web. The marking particles interposed between the web and the copy sheet are heated. After cooling, the copy sheet is separated from the web with the marking particles remaining affixed thereto.

摘要： An electrophotographic printing machine in which a developer roller transports a developer material comprising carrier granules and toner particles closely adjacent to an electrostatic latent image recorded on a photoconductive surface so as to develop the latent image with the toner particles. A member is positioned closely adjacent to the developer roller to attract the toner particles to at least one surface thereof. A beam of energy is transmitted through the member onto the surface on which the toner particles adhere. The internal angle of incidence of the beam of energy is greater than the critical angle of incidence of the member. The intensity of the beam of energy internally reflected through the member is detected. A signal indicative of the quantity of toner particles attracted to the surface of the member is generated. The signal is processed and a signal transmitted indicating the end of the useful life of the developer material.

摘要： A tandem tri-level architecture. Three tri-level engines are arranged in a tandem configuration. Each engine uses one of the three primary colors plus one other color. Spot by spot, two color tri-level images can be created by each of the engines. The spot by spot images are transferred to an intermediate belt member, either in a spot on spot manner for forming full color images or in a spot next to spot manner to form highlight or logo color images. The images created by the tri-level engines can also be transferred to the intermediate in a manner such that both spot next to spot and spot on spot transfer is effected.
