Summary:PROBLEM TO BE SOLVED: To reduce friction with a surface of a cleaning blade and improve durability.SOLUTION: A cleaning blade 7 has a peak position (Zm) inside a contact surface 7C in contact with a cleaning target member at which the Young's modulus becomes maximum. The value of the Young' modulus on the contact surface 7C is Yc, the value of the Young's modulus at the peak position (Zm) is Ym, and the value of the Young's modulus at a predetermined position (Zb) separated from the contact surface 7C with respect to the peak position is Yb. The Young's modulus of the cleaning blade 7 is controlled to establish the relationship: Ym>Yc>Yb.SELECTED DRAWING: Figure 4 【課題】クリーニングブレードの表面の低摩擦化を図ると共に、耐久性を向上させる。【解決手段】クリーニングブレード７は、被クリーニング部材に当接する当接面７Ｃの内側に、ヤング率が極大値となるピーク位置（Ｚｍ）を有する。当接面７Ｃにおけるヤング率の値をＹｃとし、ピーク位置（Ｚｍ）におけるヤング率の値をＹｍとし、ピーク位置よりも当接面７Ｃから離れた所定位置（Ｚｂ）におけるヤング率の値をＹｂとする。このとき、Ｙｍ＞Ｙｃ＞Ｙｂの関係が成立するように、クリーニングブレード７のヤング率を制御する。【選択図】図４
