Abstract
An image reader includes a reading device to read an image on a recording medium, a first conveying roller pair upstream of the reading device in a conveyance direction of the recording medium, a second conveying roller pair downstream of the reading device in the conveyance direction, to hold the recording medium together with the first conveying roller pair to convey the recording medium, and a driver to drive the first conveying roller pair and the second conveying roller pair so that a relative relation between a reading position of the reading device and the recording medium held by the first conveying roller pair and the second conveying roller pair is constant. The reading device determines that the image read from the recording medium is effective in a period in which the relative relation is constant.
