  • Publication number: 20090243207
    Abstract: A conveying body that can attract and peel-off a recording medium by a simple mechanism, and an image forming device using the conveying body are provided. One end portions of through-holes of a drum are blocked by a blocking member, and a suction member and a blowing-out member are provided at other end portions of the through-holes. Due to a suction pump being operated and suction force being generated within the through-holes via a suction port of the suction member, the suction force passes through the through-holes and acts on long grooves of an outer peripheral surface of the drum, and a sheet can be attracted reliably to the outer peripheral surface of the drum. Further, because air is blown-out from the blowing-out member by operation of the suction pump, a leading end portion of a sheet can be reliably peeled-off from the outer peripheral surface of the drum.
