An ink fountain device includes a fountain roller, a blade, a pair of ink dams, a compression coil spring, and a fountain roller moving device. The fountain roller is rotatably supported by an eccentric bearing. The blade is arranged close to the fountain roller. The distal end of the blade forms a clearance, with respect to an outer surface of the fountain roller, where ink is to be supplied. The pair of ink dams are arranged to be substantially perpendicular to the blade and oppose each other in an axial direction of the fountain roller, and are supported to be movable toward and away from the outer surface of the fountain roller. The compression coil spring biases the ink dams to move toward the outer surface of the fountain roller. The fountain roller moving device pivots the eccentric bearing so as to move the fountain roller. The pair of ink dams are moved by a biasing force of the compression coil spring in a direction substantially perpendicular to a line that connects an axis of the fountain roller and a pivot center of the eccentric bearing.
