A reference mark forming device configured to form reference marks on a recorded material to be transported in a predetermined transporting direction by a transporting device at a predetermined regular pitch in the transporting direction including: a reference-mark-specific head configured to form the reference marks on the recorded material transported by the transporting device; a mark detection sensor configured to detect the reference marks formed on the recorded material by the reference-mark-specific head on the downstream side of the reference-mark-specific head in terms of the transporting direction; and a head drive unit configured to drive the reference-mark-specific head on the basis of an output signal from the mark detection sensor, in which the reference-mark-specific head and the mark detection sensor are arranged so that the relative positional relation is maintained constant.
