    摘要： An ink for a liquid electrophotographic color printing system is optimized to reduce the lowering of image density due to wash-off, to obtain a stable over-toned color, and to have a wide reproducible color gamut. The ink includes a plurality of toners for yellow (Y), magenta (M) and cyan (C), each toner being provided in a respective one of a plurality of developing devices, and each toner having a pigment (p) for forming an image having a predetermined color, a binder (b) for binding the pigment on printing paper, a charge controller for imparting electrical properties on the toners, and a stabilizer. A carrier transfers the toners from the developing devices to a photoreceptor belt during development. The blending ratio (b/p) of the binder (b) to the pigment (p) of each toner for yellow (Y), magenta (M) and cyan (C) satisfies the following expressions: b/pyellow(Y)=5±1; b/pmagenta(M)=7±1; and b/pcyan(C)=8±1.

    摘要： A development apparatus of a liquid electrophotographic printer includes a photoreceptor web having an image area where an electrostatic latent image is formed and a non-image area at both sides of the image area. A development roller is installed to correspond to the image area to which a development electrical potential of a predetermined level is applied, in which developer is supplied to the electrostatic latent image. A squeegee roller removes developer remaining on the photoreceptor web, and an air injection nozzle is installed adjacent to both ends of the development roller. The air injection nozzle injects air to move developer remaining on the photoreceptor web from the non-image area to the image area so that a boundary line between the image area and the non-image area is prevented from being developed due to a difference in electrical potential therebetween.

    摘要： An image forming apparatus includes a plurality of image forming units, each unit developing a latent image formed on a respective photosensitive drum with a respective color toner to form an image on a sheet of paper. The image forming apparatus includes an exposing optical device for projecting light on the photosensitive drums, a first movable mirror for reflecting the light along a first optical path and a second movable mirror for reflecting the light reflected from the first movable mirror to a selected photosensitive drum along a second optical path. The first and second movable mirrors move so that the optical path lengths are constant irrespective of the position of the selected photosensitive drum. Latent images, each having a uniform size, are formed on the photosensitive drums.

    摘要： A roller separating device automatically separates a pressure roller from a heat roller when the rollers are unable to rotate or when a fixing operation is not in progress. The roller separating device includes an idle gear engaged with a pressure roller gear, a cam driving gear engaged with the idle gear, an electronic clutch fixed to a cam shaft to which a cam is also fixed. The electronic clutch is detachably coupled to the cam driving gear. The cam is driven by a driving force of a power gear and the electronic clutch couples/uncouples the driving force to the cam. When the electronic clutch is actuated, a driving force of the cam driving gear is transferred to the cam to move a pressure roller support frame so that the pressure roller is separated from the heat roller. When the electronic clutch is inactuated, the pressure roller support frame returns to its normal position by an elastic force of a spring so that the pressure roller contacts the heat roller.

    摘要： A micro electro mechanical systems (MEMS) microphone, and a method of manufacturing the MEMS microphone having an interval between a membrane and a back plate, the interval being correctly adjusted by forming the membrane and the back plate after an air-gap forming portion on a silicon substrate. Since the membrane and/or the back plate are/is formed by electroless plating, a sacrificial layer is easily planarized, and a residual stress is easily removed or controlled. The MEMS microphone includes a silicon substrate in which a back chamber is formed and on which an air-gap forming portion is formed above the chamber by etching the silicon substrate to a predetermined depth above the chamber; a membrane formed on the air-gap forming portion of the silicon substrate or the silicon substrate; and a back plate that is formed on the air-gap forming portion or the silicon substrate so as to be spaced apart from the membrane, wherein an air gap is formed between the membrane and the back plate.
