A stencil printing machine includes a drum on which a stencil sheet is mounted, and a pressure roller which presses a print sheet fed between the drum and the pressure roller and rotates together with the drum. The print sheet is fed from an upstream side of the pressure roller in a conveying direction, an image is transferred from the stencil sheet onto the fed print sheet in a process where the print sheet passes between the drum and the pressure roller, and the print sheet on which the image is transferred is discharged to a downstream side of the pressure roller in the conveying direction. A suction port forming plate taking a surface thereof as a sheet conveying surface is provided at a position close to a downstream peripheral surface of the pressure roller in the conveying direction, a suction port surrounded by the suction port forming plate and the peripheral surface of the pressure roller is provided, and a suction fan which sucks the air on an outer side of the sheet conveying surface from the suction port is provided.
