A plurality of nip rollers are provided under a driving roller approximately in a direction of a drive shaft of the driving roller. Respective shafts of the nip rollers are arranged so that the rotary shafts are inclined toward a downstream side in a transport direction of a recording medium with respect to the drive shaft of the driving roller. Nip positions for the recording medium, formed by the nip rollers and the driving roller, are positioned on an upstream side in the transport direction above the lowermost end portion of the outer circumference of the driving roller. Therefore, the recording medium is transported at a satisfactory accuracy in an image-recording section, thereby avoiding the deterioration of the recording quality which would be otherwise caused by the positional deviation of the recording on the recording medium.
