摘要： An image reading device includes a background member, an illumination unit opposed to the background member, and a reader. The illumination unit emits light to a recording medium having an image thereon. The reader receives a reflection from the recording medium to read the image. The background member has a facing surface that faces the recording medium. The facing surface includes a reference portion on a center portion in a width direction of the background member. The reference portion has a higher reflectance than an end portion of the facing surface in the width direction.

摘要： An image reading device includes a plurality of image reading units arranged at different positions in a width direction perpendicular to a conveyance direction of a recording medium to read an image on the recording medium at image reading positions and a conveyance roller pair that conveys the recording medium to the plurality of image reading units. The conveyance roller pair includes a drive roller and a driven roller that contacts the drive roller and rotates following the drive roller. The plurality of image reading units includes an upstream and a downstream image reading units downstream from the upstream image reading unit in the conveyance direction. A reading interval between the image reading positions and a diameter of the drive roller satisfy the relation: X2=n1×π×D1a, where X2 represents the reading interval, n1 represents an integer, and D1a represents the diameter of the drive roller.

摘要： A multi-beam scanning device is provided with a light source that emits a plurality of light beams, a polygonal mirror that deflects the light beams emitted by the light source to scan, and an optical system that converges the deflected light beams on a plurality of objects to be scanned. The optical system includes an optical path turning system that turns optical paths of the deflected light beams, respectively. The optical path turning system is constructed such that optical path lengths of the optical path of the deflected light beams are the same, and one of the optical paths directed to an object located farthest from the polygonal mirror consists of two linear paths and one turning portion at which a beam is deflected.

摘要： A conveyance apparatus includes a plurality of conveyors and an image reader. The plurality of conveyors conveys a recording material. The image reader reads a pattern image on the recording material being conveyed. The conveyance apparatus further includes circuitry to control the image reader. The circuitry controls the image reader to read the pattern image on the recording material in a period including a timing at which a trailing edge of the recording material being conveyed by at least two of the plurality of conveyors exits an upstream conveyor among the at least two of the plurality of conveyors in a direction of conveyance of the recording material.

摘要： A conveyance control device includes a fixing device including a first rotary body, a cooling device including a second rotary body, and control circuitry. The circuitry records a first drive amount for the second body when the first and second bodies are driven at a speed, a second drive amount for the second body when the second body is driven without the first body being driven, a third drive amount for the second body when the second body is driven to rotate faster than a rotating speed and the first body is driven, and a fourth drive amount for the second body when the second body is driven to rotate slower than the rotating speed and the first body is driven. The circuitry performs correction based on the drive amounts in such a manner that a drive amount of the second body becomes equivalent to the second drive amount.

摘要： An image forming apparatus includes image carriers for four fundamental colors of black, cyan, magenta, and yellow, and for an auxiliary color, and three optical scanning devices. A first optical scanning device includes two light sources for the black color and another fundamental color, a first deflector, and a first housing. A second optical scanning device includes two light sources for other two fundamental colors, a second deflector, and a second housing. A third optical scanning device includes a light source for the auxiliary color, a third deflector, a third housing, and one or more reflecting mirrors. The light source for the auxiliary color is disposed closer to the third deflector with the one or more reflecting mirrors to turn an optical path therebetween while maintaining an optical path length thereof. The optical paths for the auxiliary color and for the black color have identical light utilization efficiency.
