A cleaning device having a cleaning blade which has its forward end pressed into contact with the surface of an organic photosensitive member rotating at a peripheral speed of at least about 26 cm/sec to scrape off and remove residual developer from the surface of the photosensitive member. The contact face of the cleaning blade in contact with the photosensitive member makes a contact angle of about 9.5 to 14.5 degrees with a tangent line to the photosensitive member at the point of contact on one side of the blade toward the direction of rotation of the photosensitive member. The cleaning blade is pressed into contact with the photosensitive member with a force of about 0.1 to 10 g/mm. This prevents the cleaning blade from becoming reversed to entail improper cleaning or to impede the rotation of the photosensitive member.
