Abstract: An image reading device includes a reader, a transparent member, an opposing member, first and second conveyance rotators, and circuitry. The reader reads a sheet. The transparent member is disposed between the reader and the sheet. The opposing member is disposed facing the reader via the transparent member. The first conveyance rotator is disposed upstream from the reader in a conveyance direction of the sheet. The second conveyance rotator is disposed downstream from the reader in the conveyance direction. The circuitry cause the first conveyance rotator and the second conveyance rotator to convey a cleaning sheet at respective conveying speeds different from each other and bring the cleaning sheet into contact with at least one of the transparent member or the opposing member.

Abstract: 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.

Abstract: A detecting device, which is included in an image forming apparatus, includes a detector configured to optically detect at least one of a position of a sheet, a position of an image formed on the sheet, and the image formed on the sheet, and a rotary body disposed at a position opposed to the detector and having a shaft, the rotary body being rotatable about the shaft in a sheet conveying direction of the sheet. The sheet is conveyed to space between the detector and the rotary body. The rotary body has a reference plane on an outer circumferential surface, a line formed on the reference plane and extending in a width direction perpendicular to the sheet conveying direction. The detector detects the line on the reference plane while the rotary body is rotating when the sheet does not intervene between the detector and the rotary body.
