PURPOSE:To prevent a toner from leaking from a contact face, by providing a sealing member to which a flexible sheet is stuck, on the contact face to the side part of a blade member of a sealing base body. CONSTITUTION:A blade 3 rocks in the direction as indicated with an arrow by making a supporting screw 10 a supporting point, and even if a blade side part 3a gnaws at a sealing member 20, the blade side part 3a slides smoothly against the surface of a sealing member 22 since a coefficient of friction of the surface of the sealing member 22 which contacts with the blade side part 3a, and the blade 3 rocks smoothly. Accordingly, press-contact force in the axial direction of a photosensitive drum 5 of the blade 3 becomes uniform, and good cleaning is executed. Also, since it is unnecessary to increase the press-contact force of the blade 3, wear of the tip edge part of the blade 3 and wear of the surface of the photosensitive drum 5 are reduced extremely, and a life of both of them can be extended. Also, the blade side part 3a contacts with the sealing member 22, pressing slightly the sealing member 20 in accordance with rocking of the blade 3, therefore, the sealing member 22 adheres closely to the contact face of the blade side part 3a, and no toner leaks from the contact face. |
