Abstract
An end seal for use in an image forming apparatus that provides increased contact pressure using projecting ribs at nip locations formed between an end of a roll and the ends of other components such as a doctor blade or flap seal and lower contact pressure along the end of the roll. Contact pressure may be varied by changing the thickness along portions of the projecting ribs or the use of transverse ribs between each of the projecting ribs and a second surface of the end seal.
