摘要： An image forming apparatus includes an information obtainer, a memory, a candidate determining unit, and an image forming device. The information obtainer obtains feature information from the target recording medium. The memory stores at least one set of recording medium information regarding the target recording medium associated with the feature information and at least one set of image forming condition information corresponding to the recording medium information. The recording medium information is identification information. The candidate determining unit determines a candidate recording medium information from the recording medium information stored in the memory based on the feature information of the target recording medium obtained by the information obtainer. The image forming device forms an image on the target recording medium based on the image forming condition information in the memory according to the candidate recording medium information determined by the candidate determining unit.

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 reading device including a reader, a position reference member, and circuitry. The position reference member has a reference pattern along a first direction of the position reference member. The circuitry is configured to detect the reference pattern of the position reference member; determine coordinates of at least two pixels in the second direction, based on the detected reference pattern; calculate a first correction value based on the coordinates determined for the at least two pixels of the reader in the second direction; detect an outer shape and a position of an image pattern on the conveyed object based on data read by the reader; obtain a difference between an image of the conveyed object, of which a shape has been corrected, and an image of the conveyed object, of which a shape has not been correction; and set a second correction value based on the obtained difference.

摘要： An optical scanner includes a light source to project light, a light deflector to deflect light, an optical element, and a holder to hold an optical element in place. The holder includes a curve adjustment mechanism, a first pressing member, a second pressing member, and a retainer. The curve adjustment mechanism adjusts a shape of the optical element in a sub-scanning direction relative to a scanning surface and perpendicular to a main scanning direction. The first pressing member is disposed at a first side from which the first pressing member presses the optical element in the sub-scanning direction. The second pressing member is disposed at a second side opposite the first side, to press the optical element from the second side. The retainer fixes substantially a center of the optical element in a main scanning direction of the light striking the optical element to the first side.
