A paper transfer device includes a paper transfer unit that transfers a paper laid on a transfer surface beneath an inkjet head, a downstream-side transfer portion that is disposed on a downstream side of the transfer unit along a transfer direction of the paper and transfers the paper along a downstream-side transfer path extending downward from the transfer surface, a paper leading portion that leads the paper from the transfer unit to the downstream-side transfer portion, and a controller that controls the paper leading portion to press the paper after a leading end of the paper is led to the downstream-side transfer portion by the paper leading portion.
