There are provided an image reading device and a printing apparatus that can reduce an influence of the shadows of suction holes. Suction holes, which are used to suck a sheet, are arranged on the peripheral surface of a drum that transports the sheet. The suction holes are arranged in grooves that are formed along a direction orthogonal to a transport direction. Accordingly, since an influence of the shadows of the suction holes can be reduced even in a case in which density unevenness is inspected on the basis of a read image, the false detection of density unevenness can be prevented.
