Abstract
A sheet transport device includes pre-transfer sheet-transport rollers that transport a sheet to a transfer position at which an unfixed image is transferred, the pre-transfer sheet-transport rollers including a first roller in which three or more separate rollers attached to a first shaft rotate, and a second roller in which three or more separate rollers attached to a second shaft are in contact with the separate rollers of the first roller and rotate. The hardness of an inner separate roller of the first roller is lower than the hardness of end separate rollers of the first roller. The outside diameter of an inner separate roller of the second roller is greater than the outside diameter of end separate rollers of the second roller.
