A conveyance device includes an image-forming drum (52) which fixes a rear surface (PB) of a sheet (P) and conveys the sheet along an arc-shaped path at a transfer position (312), a chain gripper which includes a gripper (64D) which is disposed on the downstream side of the image-forming drum in a conveyance direction and holds a leading end portion of the sheet, conveys the sheet along the arc-shaped path at the transfer position, and is disposed at a position at which a portion of the path leads to the image-forming drum side from the transfer position, and a blower unit (300) which is disposed on the chain gripper side from the transfer position, blows air from the chain gripper side to the image-forming drum side on the downstream side of the transfer position in the conveyance direction, and blows air toward the sheet conveyed by the chain gripper.
