An inking device for feeding ink that is fed to an ink rail to a printing plate on a plate cylinder via a group of rollers that are sequentially in contact with each other, comprising a first roller part of the outer periphery of which faces an ink feeding surface of the ink rail, a second roller that is disposed downstream of the first roller in the ink feeding process and in contact with the outer periphery of the first roller on the downstream side in the rotating direction from the position at which the first roller faces the ink feeding surface of the ink rail, a third roller that is in contact with the first roller on the downstream side in the rotating direction from the position at which the second roller comes in contact with the outer periphery of the first roller, and a fourth roller that is in contact with the outer peripheries of the second and third rollers and blocks the front side in the rotating direction of the first and second rollers at the position where the first and second rollers are in contact with each other; ink droplets and ink particles produced at the contact area of the first and second rollers by the rotation thereof being contained in a space enclosed by the first through fourth rollers.
