PROBLEM TO BE SOLVED: To miniaturize a blade assembly and a developing device while reducing distortion of a thickness regulation blade. SOLUTION: The blade assembly 100 includes the thickness regulation blade 110, and a blade holder 120 and a blade reinforcement plate 130 for supporting the thickness regulating blade 110 on the developing device. The blade holder 120 includes a first nipping surface 121A and a first fixing surface 122A extending in a direction different from the first nipping surface 122A, and the blade reinforcement plate 130 includes a second nipping surface 131A and a second fixing surface 132A extending in a direction different from the second nipping surface 131A. The thickness regulation blade 110 includes a positioning opening 113 and is sandwiched between the first nipping surface 121A and the second nipping surface 131A. The blade holder 120 and the blade reinforcement plate 130 are mutually fixed at mounting parts 122 and 132, and mounted on the developing device at the mounting part 122, and the first nipping surface 121A includes a projection 123 which is fitted into the positioning opening 113.
