The blade is attached so as to be movable and not come off, and when the electrostatic latent image carrier rotates, the blade is biased by frictional force, so that the end of the blade in the opposite direction from the cleaning edge aligns with the straight line formed on the support member. A cleaning device characterized by: being in pressure contact with a regulating portion having a shape.
