ムクリーニング装置。 Drum cleaning involves bringing a blade made of an elastic material into contact with a photosensitive drum of an image forming apparatus that forms hard copies using electrophotography to clean toner adhering to the surface of the photosensitive drum after transfer. The apparatus includes a transfer unit disposed above the photosensitive drum, the photosensitive drum transferring the image onto a recording paper at the above position, and the photosensitive drum being rotated at a position below a horizontal line passing through the center of rotation of the rotating photosensitive drum and above the photosensitive drum. The installation direction range of the blade is set in a region on the opposite side of the rotation direction of the photosensitive drum from a vertical line passing through the center of rotation, and a horizontal line passing through the intersection of an extension line of the installation direction of the blade and the surface of the photosensitive drum; A drum cleaning device characterized in that an elastic blade is arranged within a range of a normal line at the intersection of an extension line in the installation direction of the blade and the surface of the photosensitive drum.
