Blade cleaning of a char e retentive surface in reproduction ap lications is

cleaning blade has certain desirable aspects, particularly its structural rigidity, in certain circumstances in use with an electroreceptor in ion deposition printing, it ap ears that the metal blade promotes ghosting, i.e.,

proposed that this is related to a discharge occurring between the the metal blade and the electroreceptor. A plastic blade, backed by a steel blade, has been found to improve the problem of ghosting. However, plastic blades tend to give early cleaning failures, by taking a set, or by uneven wear near the blade ends.
