An inkjet printing machine includes: a paper feeder; a transfer unit having a conveyer belt with a plurality of suction holes formed thereon and transferring a sheet fed by the paper feeder while sucking and holding the sheet on the conveyer belt by suction force generated at the suction holes; inkjet heads discharging ink on the transferred sheet; and a controller performing printing by controlling the above components, wherein the suction holes of the conveyer belt are arranged so that, when the leading edge of the sheet in the transfer direction does not overlap with the suction holes, the trailing edge of the sheet also does not overlap with the suction holes, and the controller controls the paper feeder to feed a sheet at a timing when the leading edge and the trailing edge of the sheet in the transfer direction do not overlap with the suction holes.
