A print unit includes, a first ejection head which ejects a first liquid, a second ejection head which ejects a second liquid and disposed on an upstream side of the first ejection head in terms of a first direction; a conveyance device which conveys a recording medium relatively with respect to the print unit; and a switch-back unit which reverses a conveyance direction of the recording medium, from the first direction, to a second direction opposite to the first direction. Only the first ejection head ejects the first liquid toward the recording medium when the recording medium is conveyed in the first direction; the switch-back unit reverses the direction from the first direction to the second direction; and only the second ejection head ejects the second liquid toward the recording medium when the recording medium is conveyed in the second direction.
