Abstract: A combination of a latent-image pattern which forms a latent-image part and a background pattern that forms a background-image part is determined so that the latent-image part and background-image part have equal print densities. The determined latent-image pattern and background pattern, color information used to determine a color of the copy-forgery-inhibited pattern image, input image information as an image to be processed, copy-forgery-inhibited pattern basic information used to designate the latent-image part and background-image part, and camouflage region designation image information used to designate a camouflage region are input. A copy-forgery-inhibited pattern image is generated on the basis of the input information.

Abstract: An image forming apparatus includes an acquiring unit that acquires image data expressing an image region included in an image with a first value and a background region included in the image with a second value; a segmenting unit that segments the image region into multiple segments arranged in a fast scanning direction; a converting unit that converts a value of at least one of the segments into the second value; an output unit that generates an image signal on the basis of the image data and outputs the image signal; an exposure unit that exposes a charged image bearing member to light according to the output image signal by scanning the light thereto in the fast scanning direction so as to form a latent image; and a developing unit that forms the image by developing the latent image using an invisible toner that absorbs infrared light or ultraviolet light.

Abstract: A conductive chassis plate faces a printed circuit board at a distance. One end of the conductive chassis plate is aligned with one end of the printed circuit board. One end of the conductive chassis plate is electrically connected to a ground wiring pattern provided on one end of the printed circuit board. One end of the conductive chassis plate is electrically connected to a conductive member that extends from one end of the conductive chassis plate toward the other end. As a result, in transmitting or receiving a signal with respect to external equipment attached to a connector, an influence of electrostatic discharge is reduced with a simple configuration.

Abstract: An optical scanning device 65 is adapted to bring a deflector mirror plane 651 into independent pivotal motions about a first axis and a second axis perpendicular to each other. A mirror driver section including a first axis driver and a second axis driver is so controlled as to bring the deflector mirror plane 651 into pivotal motion about the first axis thereby deflecting a light beam L for scanning along a main scan direction. On the other hand, the deflector mirror plane 651 is pivotally moved about the second axis thereby to adjust the scanned beam L for its position on a photosensitive member 2 with respect to a subscan direction. Thus, even if the scanned beam is deviated from a reference scan position with respect to the subscan direction due to component tolerances or assembly errors, such a deviation can be corrected.

Abstract: Improved apparatus and methods for displays are disclosed that utilize light concentration array between mechanical light modulators and the viewing surface of the display. The light concentration array includes an array of optical elements that concentrate light on respective ones of the light modulators to maximize the contrast ratio and off axis viewing of the display.

Abstract: In this invention, the charging units are in the separate construction for the main chargers and for the ozone ducts. When installing the process units, the ozone ducts are placed on the elastic sheets of the duct cases that are fixed to the main frame. The process units are slid while slanting the ozone ducts to the duct cases by the main chargers against the bias force of the elastic sheets. Fluctuation in manufacturing accuracy is absorbed by the elastic sheets and the maintenance efficiency when installing/removing the process units is improved by sliding the process units smoothly. Further, the charging units are supported certainly by the main frame.

Abstract: A locking apparatus includes a lever unit disposed at an intermediate transfer belt frame to cause an intermediate transfer belt to contact a photosensitive medium; a locking unit disposed at a supporting cover to cause the supporting cover to be fixed to and separated from an engine frame; and a coupling unit to cause the lever unit to operate in association with the locking unit.

Abstract: A system for printing is described. The system uses at least one cantilever, and more typically a plurality of cantilever to transfer charge, either to or from a dielectric surface. The resulting charge distribution represents an image. Toner deposited over the dielectric surface is attracted to the charged portions of the dielectric. Thus the toner also forms the image. The toner image is then transferred and affixed to a printing surface.

Abstract: A donor member, useful in ionographic or electrophotographic apparatuses and preferably useful in hybrid scavengeless development units, has a substrate and an oxidized transport coating thereover. The oxidized transport coating includes a polymer binder, charge transporting molecules and one or more oxidizing agents. The polymer binder of the donor roll coating preferably includes one of (1) a crosslinked polymer with charge transporting molecules dispersed therein, or (2) a crosslinked polyamide binder with hydroxy charge transport molecules dispersed therein. The donor roll is preferably included in a printing machine that develops latent images formed on a photoconductive member.

Abstract: A reversible image display medium including two sheets; one or more developer accommodating cells formed between the two sheets, and each having a periphery surrounded by a partition wall; and dry developer contained in each of the cell(s), wherein the dry developer contains at least two kinds of frictionally chargeable dry developer particles having different chargeable polarities and different optical reflection densities. The image is displayed by forming a predetermined electrostatic field for each pixel in accordance with the image to be displayed and thereby moving the developer particles in a frictionally charged state. The image formed on the reversible image display medium can be erased, e.g., by an image erasing device.
