Abstract
A medium-transporting apparatus has a carrier belt which carries a medium attracted thereto. An attraction roller is disposed in an abutting relation with the carrier belt. The print medium is sandwiched and passes between the attraction roller and the carrier belt. The attraction roller has a low resistance resilient roller and a high resistance member of an insulating material or a semiconductive material formed on the surface of the resilient roller. The member has a higher electrical resistance than the print medium and prevents current from flowing through areas in which the print medium is absent between the attraction roller and the carrier belt. The attraction roller receives a high voltage so that a discharge occurs between the attraction roller and the print medium when the print medium separates from the attraction roller as the print medium passes between the attraction roller and the carrier belt, thereby depositing charges on the print medium so that the print medium is electrostatically attracted to the carrier belt.
