Claim:
An inkjet printer comprising: a first transport roller driven in a direction for transporting a sheet; a plurality of first driven rollers configured to press a sheet against the first transport roller in such a manner that the sheet is nipped between the first driven rollers and the first transport roller; a second transport roller driven in the direction, the second transport roller being positioned downstream of the first transport roller in a sheet transporting direction; a plurality of second driven rollers configured to press a sheet against the second transport roller in such a manner that the sheet is nipped between the second driven rollers and the second transport roller; an inkjet print head configured to eject ink drops on a sheet while being reciprocated along a perpendicular direction to the sheet transporting direction, the inkjet print head being positioned between the first transport roller and the second transport roller; and a holder assembly including: a plurality of holders for mounting the respective first driven rollers in such a manner that the first driven rollers are supported individually rotatably at different locations along the perpendicular direction while being arranged in different groups of one or more on different lines parallel to the perpendicular direction; a support for supporting the holders; and a plurality of urging members for urging the respective first driven rollers against the first transport roller through the respective holders, wherein the urging members are configured to urge a more downstream one of the groups in the sheet transporting direction against the first transport roller with a weaker total force.
