PURPOSE:To stabilize a blade, and to improve continuously the linearity of a cleaning edge by constituting a titled device so that a cleaning blade positioning wall is held strongly by a projecting part of a blade fitting groove. CONSTITUTION:A blade fitting groove 4 for inserting a cleaning blade 3 is opened and provided on a blade holding member 2. As for the blade fitting groove 4, an upper wall A1 of the first holding member 2a and an upper wall B1 of the second holding member 2b being roughly parallel to each other are formed in a blade inserting port 5, also an intermediate wall A2 and an intermediate wall B2 being roughly parallel to each other are formed in the intermediate half part, and an upper wall A3 and a lower wall B3 being roughly parallel to each other in the same way are formed in the inner part, and also a blade positioning wall 6 is formed in parallel to a shaft of a photosensitive body 1 is formed in the innermost part. The part of the intermediate walls A2, B2 has such a shape as a bend part is constituted with respect to the upper walls A1, B1 and the lower walls A3, B3 and also a width of the blade fitting groove 4 is formed so as to be a little larger than a plate thickness of the cleaning blade 3. |
