ABSTRACT:
A follower roller is brought into press contact with a driving roller by a load having a predetermined value, thereby being rotated in accordance with a rotation of the driving roller to transport the medium clamped therebetween in a first direction. The follower roller includes a shaft portion and a roller body provided so as to surround the shaft portion. The follower roller is configured such that a value of a ratio f/F is not greater than 0.03. Here, F is a force transporting the medium in the first direction which is generated by the load, and f is a resistance force generated in a second direction opposite to the first direction by a friction loss of the shaft portion of the follower roller which is generated by the load.
