1. A sheet transport device comprising:
a curved sheet transport path;
a plurality of transport roller pairs disposed in the sheet transport path;
a plurality of driving sources that drive the plurality of transport roller pairs;
a plurality of load detectors that detect the loads of the plurality of driving sources; and
a control unit that:
controls a driving speed of at least one of the driving sources such that detection results obtained by the load detectors are within a predetermined range, and
controls to adjust the driving speed of the at least one of the driving sources based on a result of a comparison of the load of at least two of the driving sources.
