PROBLEM TO BE SOLVED: To provide a record medium transport device, finely adjusting the transport amount of a record medium by changing the biting amount of a projection formed on the surface of a transport roller to the record medium to vary the virtual feed diameter by the transport roller, and provide an ink jet recording apparatus including the device. SOLUTION: In this record medium transport device, the record medium P is held and transported by the transport roller 1 driven by a driving means 3 and provided with a number of projections formed on the surface thereof and a pressure roller 2 disposed opposite to the transport roller 1. The transport device is provided with a pressure changing means for changing the pressing force of the pressure roller 2 to the record medium P, and the pressing force of the pressure roller 2 is changed by the pressing force changing means to change the biting amount of the projections to the record medium P, thereby varying the transport amount of the record medium P. This ink jet recording apparatus includes the device. COPYRIGHT: (C)2005,JPO&NCIPI
