Patent ID: 8177231

Claim:
An image forming device comprising: a recording head expelling droplets toward a recording medium; and a conveying body that rotates, faces the recording head and conveys a recording medium, the conveying body comprising: a cylindrical-tubular portion whose outer peripheral surface is a conveying surface for conveying the recording medium; a plurality of groove portions formed in the outer peripheral surface of the cylindrical-tubular portion; a plurality of air paths communicating with the groove portions and formed along a peripheral direction of the cylindrical-tubular portion, the air paths extending in an axial direction of the cylindrical-tubular portion and including first path openings and second path openings; wherein the first path openings are provided at a first end surface of the cylindrical-tubular portion, and the second path openings are provided at an opposite second end surface of the cylindrical-tubular portion, wherein the first path openings of the air paths are blocked by a blocking member that contacts the first end surface of the cylindrical-tubular portion, wherein the blocking member includes an open region that opens one path of the air paths at a position of recording by the recording head, the conveying body further comprising: a suction member sucking air from second path openings of the air paths that have rotated and come to a suction position; and a blowing-out member provided adjacent to the suction member, and blowing-out air to the second path openings of the air paths that have come to a blowing-out position, wherein the first openings of the air paths are blocked by a blocking member that contacts an end surface of the cylindrical-tubular portion, wherein a suction port of the suction member is formed in a shape of an arc along the peripheral direction of the cylindrical-tubular portion, and a blowing-out port of the blowing-out member is provided at an end portion of the suction port or provided separately, wherein second path openings of the air paths, that are positioned at a leading end portion of the recording medium when conveying of the recording medium starts, communicate with the suction port of the suction member, and second openings of the air paths, that are positioned at a trailing end portion of the recording medium when conveying of the recording medium ends, communicate with the blowing-out port of the blowing-out member.
