Abstract

PURPOSE: To prevent the developer from spilling over by transferring it into the quartered circumferential part to hold temporarily, by pressing the end part of elastic cleaning plate blade which abuts against the image carrier plane against the carrier plate by constituting a protruding part composed of quartered circumferential conductive elastic wall.
CONSTITUTION: A blade 2 supported on a stiff holder 1 is sufficiently pressed against a photosensitive drum 3, which is an image carrier, at blade main body part 2a and protruding parts 2b provided at both ends thereof. The blade part 2a is more strongly rubbed against the blade main body, so that the toner remaining on the photosensitive drum may be sufficiently removed. Furthermore, since the end part protruding parts 2b are in perfect contact with the photosensitive drum due to extreme elasticity, the toner is kept from spilling over the end parts. The part collecting the toner at said protruding parts 2b makes up a wall composed of quartered circumferential plane. Since the back side of the circumferential wall is notched, an elastic, thin wall is constituted. The toner collected in the circumferential wall is caused to move in the central direction of the blade 2 along the locus of this quartered circumference, thus preventing the toner from spilling over the blade ends.
