Claim:
A roll recording material transport device comprising: a driving side roll holder and a driven side roll holder attached to respective ends of a roll portion of a roll of recording material; a driving side spindle and a driven side spindle that engage with the driving side roll holder and the driven side roll holder, respectively, and support the roll portion; a spindle driving source that rotates the driving side spindle in the forward direction and the reverse direction; a driving side support mechanism and a driven side support mechanism that support the driving side spindle and the driven side spindle, respectively; a transport roller that pinches and transports the roll of recording material pulled out from the roll portion; and an assist executing section that executes assist control in which a rotating force in the direction of transporting the roll of recording material is applied by the spindle driving source through the driving side spindle and the driving side roll holder in an engaged state to the roll portion, wherein the frictional force between the driving side spindle and the driving side roll holder is set smaller than the frictional force between the driven side spindle and the driven side support mechanism.
