A stencil printer has a printing drum which has an ink-permeable peripheral wall around which a stencil master is wound and to the inner surface of which ink is supplied. The printing drum is rotated about its longitudinal axis. An internal press roller is disposed inside the printing drum and is rotated in contact with the inner surface of the peripheral wall of the printing drum. A paper pinch drum is disposed outside the printing drum and is pressed against the peripheral wall of the printing drum with a printing paper pinched between the pinching means and the stencil master wound around the peripheral wall. A retainer roller is disposed in a predetermined position near the internal press roller and the inner surface of the peripheral wall downstream of the contact line between the internal press roller and the inner surface of the peripheral wall in the direction of rotation of the printing drum.
