The conveyance mechanism 11 of a printer 1 has a conveyance roller 22, and first and second roller segments 23(1), 23(2). The hardness of the first roller segment 23(1) is lower than the hardness of the second roller segment 23(2), and is pushed against the conveyance roller 22 with greater pressure than the second roller segment 23(2). Skewing of the recording paper 3 due to variations in the conveyance roller 22 can therefore be prevented or suppressed because the nip width N1 of contact in the conveyance direction D between the outside surface 23a of the first driven roller 23 and the conveyance roller 22 is greater than the nip width N2 of contact in the conveyance direction D between the outside surface 23a of the second driven roller 23 and the conveyance roller 22.
