Abstract
A transport roller for a printing apparatus transports a medium. The transport roller includes a shaft that extends in a direction intersecting a transport direction of the medium, and a wheel group in which a plurality of toothed wheels arrayed in the direction in which the shaft extends are held by holders. The toothed wheel includes non-formation portions having no teeth. The non-formation portions of the plurality of toothed wheels of the wheel group are arranged with an interval therebetween in a circumferential direction of the toothed wheels. The non-formation portions are cut portions that are formed when the toothed wheel is cut off from a base. The teeth other than the teeth adjacent to the cut portions are arranged away from each other at regular intervals in a circumferential direction of the wheel group.
