Summary:To provide a developing device that can prevent a blade rubber part from excessively pressing a peripheral surface of a developing roller.SOLUTION: A layer thickness regulation blade 6 comprises: a support sheet metal 11; and a blade rubber part 12. The support sheet metal 11 has a leading end part 11C and a base end part 11D. The base end part 11D is attached to a housing 2. The blade rubber part 12 is supported by the leading end part 11C of the support sheet metal 11. The blade rubber part 12 is in contact with a peripheral surface of the developing roller 3. The support sheet metal 11 has a slit 112A. The slit 112A is located at a first end 11A of the support sheet metal 11. The slit 112A extends in an axial direction.SELECTED DRAWING: Figure 5 【課題】ブレードゴム部が現像ローラの周面を過度に押圧することを抑制できる現像装置を提供する。【解決手段】層厚規制ブレード６は、支持板金１１と、ブレードゴム部１２とを備える。支持板金１１は、先端部１１Ｃと基端部１１Ｄとを有する。基端部１１Ｄは、筐体２に取り付けられる。ブレードゴム部１２は、支持板金１１の先端部１１Ｃに支持される。ブレードゴム部１２は、現像ローラ３の周面に接触する。支持板金１１は、スリット１１２Ａを有する。スリット１１２Ａは、支持板金１１の第１端部１１Ａに位置する。スリット１１２Ａは、軸方向に延びる。【選択図】図５
