摘要： The surface-treated doctor blade having nickel-phosphorus-based alloy plating which does not include irregularities of planar diameter exceeding 50 μm at least at the blade edge end can have an improved conformability of blade edge and at the same time improved wear resistance of the blade edge, thereby enabling reduction in exchange frequency of the blades. Moreover, it is preferable that the plating include 20 or less irregularities of planar diameter more than 30 μm per 1 m in the longitudinal direction, more preferably the plating includes 10 or less irregularities of planar diameter more than 20 μm per 1 m in the longitudinal direction, particularly preferably the plating includes 5 or less irregularities of planar diameter more than 10 μm per 1 m in the longitudinal direction.
