ABSTRACT:
A cleaning device of an image-forming apparatus includes a soft elastic member movable in the direction of the axis of the shaft line of an elastic blade, and an interlocking mechanism for moving and separating the soft elastic members toward and away from each other during the rotation of the elastic blade. The soft elastic members may be engaged with the end of the blade when a pointed edge of the blade is engaged with a surface of a photoreceptor, and the soft elastic members may be separated from the ends of the blade when the pointed edge of the blade is positioned away from the surface of the photoreceptor. The elastic members do not interfere with the rotation of the blade when the pointed edge of the blade is positioned adjacent the surface of the photoreceptor. And, since the elastic members are engaged with the ends of the blade while the pointed edge of the blade is engaged with the surface of the photoreceptor, the scattering of the toner from the ends of the blade can be prevented.
