A paper surface cleaning device for cleaning a surface of a printing paper running before being fed to a printing portion of a printing machine, which comprises a cleaning sheet having a water holding capacity in contact with the surface of the printing paper with a difference in running velocity between the printing paper and the cleaning sheet, a dampening roller which has, at its surface, a wettability so that water is attached to the surface of the dampening roller and which functions to push the cleaning sheet onto the surface of the printing paper, and a water pan into which the dampening roller is dipped partially. An even water film can be formed on the surface of the dampening roller to enable the cleaning sheet to get wet uniformly in its widthwise direction.
