20120163783 | SYSTEM AND METHOD FOR ILLUMINATING AND IMAGING THE IRIS OF A PERSON - A system and method for capturing an image of one or both irises. To image an iris, a person stands or moves in a target zone. A flash element provides an incoherent flash of light through an aperture. The flash is filtered to produce filtered light. The filtered light has primary wavelengths in the far red and near infrared portions of the spectrum. The filtered light is not perceived well by the human eye due to short duration, NIR color and small size. The intensity of the filtered light at the target area surpasses the intensity of all ambient light. In this manner, a person's face in the target area will always be properly illuminated, even if that person were backlit by full sunlight. An image of the person's face is taken with a camera. The image of the face is analyzed to obtain any iris pattern information. | 2012-06-28 |

20120163878 | DEVELOPING DEVICE - A developing device includes a developing sleeve for carrying a developer containing a magnetic carrier and a non magnetic toner; a magnet, provided in the sleeve and including a plurality of magnetic poles disposed along a circumferential direction of the sleeve, for carrying the developer on the sleeve; and a regulating member, provided opposed to the sleeve with a predetermined spacing in a region in which the magnetic poles different in polarity are adjacent to each other, for regulating an amount of the developer carried on the sleeve. The magnetic poles are disposed so that a circumferential direction component of a magnetic force acting on the magnetic carrier contacting at least a part of an upstream regulating surface of the regulating member with respect to the circumferential direction of rotation of the sleeve is opposite from the circumferential direction of the rotation. | 2012-06-28 |
20120163879 | Developing device and image forming apparatus including the same - A developing roller including a housing containing toner; and a developing roller installed in the housing and supplies the toner to an electrostatic latent image formed on a photoconductor, the developing roller including a cylindrical unit in the form of a hollow pipe and a power transmission unit connected to one end of the cylindrical unit and connected to a power transmission member for rotating the developing roller. Both ends of the cylindrical unit are supported by the housing and the power transmission unit is not restricted by the housing. Both ends of the cylindrical unit are supported by the housing and the power transmission unit is not restricted by the housing. | 2012-06-28 |
20120163880 | METHOD FOR CONTROLLING IMAGE FORMING APPARATUS, AND IMAGE FORMING APPARATUS - If any of a plurality of conditions is satisfied, an image forming apparatus having a plurality of image forming units that form images on an intermediate transfer member in a superimposed manner detects, using a pattern detection sensor, the amount of color misregistration of the images formed by the plurality of image forming units on the intermediate transfer member and corrects the color misregistration of the images formed by the plurality of image forming units in accordance with the amount of color misregistration that is smaller than a color misregistration correction tolerance, which varies depending on the plurality of conditions, and that has been detected by the pattern detection sensor. | 2012-06-28 |
20120163881 | POLYIMIDE INTERMEDIATE TRANSFER BELT - Exemplary embodiments provide an intermediate transfer belt, materials and processes for producing an intermediate transfer belt, and an image transfer apparatus used in electrophotographic printing devices, wherein the intermediate transfer belt can comprise a thermosetting polyimide comprising the reaction product of a polyamic acid and a hydroxyl-terminated polybutadiene. | 2012-06-28 |
20120163882 | FUSING DEVICE AND IMAGE FORMING APPARATUS HAVING THE SAME - A fusing device to reduce lubricant leakage, includes a fusing belt having a heat source placed therein, a pressure roller placed to apply pressure to an outer surface of the fusing belt, and a nip plate to support an inner surface of the fusing belt so as to define a fusing nip between the fusing belt and the pressure roller. The nip plate includes a stepped portion spaced apart from the inner surface of the fusing belt so as to define a space for accommodation of a lubricant applied to the inner surface of the fusing belt. The fusing device may further include a side frame to rotatably support a longitudinal end of the fusing belt. The side frame may be provided with a lubricant guide to guide the lubricant on the longitudinal end of the fusing belt toward the center of the fusing belt. | 2012-06-28 |
