PROBLEM TO BE SOLVED: To provide a developing blade capable of forming a clear image for an electrophotographic device or an electrostatic photographic device by preventing from making a character bolder. SOLUTION: As for the developing blade of centrifugal molding for controlling the toner layer on developing roller periphery in a specified thickness, composed by connecting the elastic blade member 3 on a supporting body 2, the developing blade is composed by making the roughness Rz of the surface 5 rubbing the developing roller of the elastic blade member 3 as 1.0 to 1.5μm, and furnishing 5 to 10μm of pitch gaps approximately parallel stripes in the lengthwise direction of the elastic blade member 3 approximately crossing the direction of rubbing the developing roller. |
