There is further provided that a liquid applying mechanism applying liquid, which is permeable to the paper dusts, onto a print surface of the print sheet to allow the paper dusts to be permeated with the liquid at an upper stream position than a position where the printing drum and the rotary printing press member are in press contact with each other in the paper feed path. A liquid applying mechanism may firstly apply the liquid onto the stencil sheet from which the liquid is transferred to a print surface of the print sheet.
