The blade device has a blade body made of urethane rubber, a surface coating layer and an underlying primer layer between the surface coating layer and the blade body, the primer layer covering an area of the blade body more extensive than that covered by the surface coating layer, the surface coating layer being provided on the region of the primer layer which is closer to the object than is a portion of the blade body where stresses are concentrated when the blade is held in contact with the object.
