To provide a surface-treated doctor blade capable of improving intimacy of the edge of a blade, improving the abrasion resistance itself of the edge of the blade, and decreasing the frequency of interchange of the blade.
The surface-treated doctor blade has no uneven part whose size in the plane direction exceeds 50 μm, and is provided with a film consisting of a nickel-phosphor alloy. It is preferable that the uneven parts have those whose sizes in the plane direction exceed 30 μm are at most 20 per 1 m in the length direction, and it is more preferable that the uneven parts whose sizes in the plane direction exceed 20 μm are at most 10 per 1 m in the length direction, and it is especially preferable that uneven parts whose sizes exceed 10 μm are at most 5 per 1 m in the length direction.
