ABSTRACT:
An ink jet printer has two first driven rollers (A) disposed at a most upstream position in a secondary scanning direction, two first driven rollers (B) disposed at an intermediate position in the secondary scanning direction, and a single first driven roller (C) disposed at a most downstream position in the secondary scanning direction. The pressing force on a trailing edge of the recording sheet (10) is dividedly released in three steps sequentially and, accordingly, the nipping force and feeding force working on the recording sheet (10) also vary stepwise. Load fluctuations that occur at the moment the trailing edge of the recording sheet (10) is released from the nipping force of the first transport roller (4) also vary stepwise, whereby it is not possible that the feed precision is disturbed in a moment.
