Provided is a paper feeding roller in which recesses due to deformation are unlikely to be formed even when contact with another roller in one location continues for a comparatively long period of time, particularly as a conveying roller or the like. A paper feeding roller that has a shaft measuring 6 mm in exterior diameter pressure-welded to the outer circumferential surface under a load of 600 g in a high-temperature environment of 60 C. for 24 hours is left at room temperature for eight hours while being pressure-welded, after which the recess amount obtained using the difference (T).sub.0T.sub.1, between the thickness T.sub.1 (mm) of the position where the shaft was pressure-welded and the thickness T.sub.0 (mm) of a position where the shaft was not pressure-welded, is 0.1 mm or less.

A feeding roller for a document conveying apparatus includes a plurality of groove portions arranged with a regular interval in a width direction of the feeding roller on a surface of the feeding roller, and a projection portion provided between each pair of adjacent groove portions to scrape off paper particles on the external peripheral. The projection portion has a regular pattern extending in the width direction of the feeding roller.

A transport device 3 includes a transport roller 53 that transports a medium P along a transport path TR of the medium P; a paper dust attracting roller 54 that is arranged at a position facing the transport roller 53 and that attracts paper dust clinging to the medium P; a paper dust removal section 55 that contacts the paper dust attracting roller 54; and a paper dust transport section 60 that is provided at a position adjacent to the paper dust removal section 55 and that transports the paper dust removed by the paper dust removal section 55, wherein the paper dust attracting roller 54 and the paper dust removal section 55 are configured such that contact pressure when the paper dust attracting roller 54 and the paper dust removal section 55 contact each other differs in an X-axial direction.
