Abstract
Sheet stripping mechanism for effecting removal of copy sheets, having toner images substantially fused thereto, from a heated fuser member forming a part of a xerographic or the like, reproducing apparatus. The sheet stripping mechanism is characterized by the provision of a stripping blade which is substantially coextensive with the dimension of the copy sheet to be stripped from the fuser member. The blade is attached to a pivotal support structure by means of a heat insulating block interposed between the blade and the pivotal support. A pair of springs serve to bias the blade into contact with the heated fuser member, the pivot point of support members being in line with the plane of the blade whereby the blade during stripping is substantially tangential to the surface of the heated fuser member.
