摘要： A developing apparatus develops an electrostatic latent image formed on the surface of an image retaining member into a visible image by the use of a developer including a magnetic carrier and a toner. The developing apparatus includes a rotatable non-magnetic sleeve retaining the developer, a permanent magnet member disposed in the non-magnetic sleeve and having a plurality of magnetic poles, a developer tank containing the developer, a toner tank containing the toner and having a toner outlet communicating with the developer tank and further having a toner replenishing movable member at the outlet, and a developer mixing movable member installed inside the developer tank. In the developer tank, a predetermined amount of the developer is contained which has previously been adjusted to a predetermined toner density. Further, the developing apparatus is constructed such that the whole of the developing apparatus is abandoned after the magnetic carrier has reached the end of its predetermined life.

摘要： A process for single-pass multi-color electrophotographic printing comprising the steps of forming first and second electrically charged oppositely polarized, latent images on a dielectric-covered photoconductive printing. First and second toners, oppositely charged and differently colored are applied to the first and second latent images, forming first and second toned images having different colors and different polarities. The toned images are then similarly charged and transferred to a print medium.

摘要： An electrographic printing apparatus capable of duplex printing comprises a housing, a source of copy material and an output tray for receiving such copy material after it is imprinted, and a photoconductive member for storing a latent electrostatic image of the information to be imprinted. The printer/copier has first and second paper paths located near the top of the housing so that access to the paper may be achieved from the top of the housing. A photoconductive member is located below the first paper path and comes into contact with a first side of the paper from below in a transfer zone located in the first paper path to imprint the first side of the paper. The second paper path is operative to receive paper after it has passed through the transfer zone and information has been transferred to the first side of the paper. As the paper travels along the second paper path, it is turned over and then returned to the first paper path prior to the transfer zone so that the second side of the paper is imprinted from below by the photoconductive member.

摘要： An electrographic printing apparatus capable of functioning as a copier, printer, and telefax machine is disclosed. The electrographic printing apparatus includes a photoconductive member, preferably a horizontally mounted photoconductive belt, a developer unit for developing an electrostatic latent image on the photoconductive member, and a biased transfer roller to transfer the developed electrostatic latent image to a sheet of copy material. The apparatus also includes an optical print head which can receive information from a local or a remote source to form the electrostatic latent image on the photoconductive member and thus act as a printer. The apparatus further includes a device for scanning an original document and for projecting the scanned image either onto the photoconductive member or onto a CCD linear array. When the scanned image is projected onto the photoconductive member, a copy of the original document is made. When the image is projected onto the CCD linear array, the scanned image is digitized and sent via the telephone lines in the manner of a telefax machine.
