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.

Roll fuser stripping mechanism

A fusing apparatus in which particles are substantially permanently affixed to a sheet. The fusing apparatus includes a fusing member operatively associated with a back-up member to define a nip through which a sheet passes. In the operating mode, the fuser member is heated to the operating temperature with liquid release material being applied thereto. The fuser member is heated to a temperature lower than the operating temperature in the standby mode. To prevent the formation of a bead release material on the fuser member in the standby mode of operation, relative movement is generated between the fuser member and backup member.

Fuser drive system

An apparatus in which a fluid release material is applied to a fuser member. The fuser member is in communication with a backup member and a sheet of support material having particles thereon passing therebetween. A sealing arrangement prevents sidewise leakage of the release material along the longitudinal axis of the fuser member.

Release material application seal

An apparatus in which a metered quantity of release material is applied to a fuser roll. The release material is heated to maintain it substantially in a fluid state.

Heated fuser release agent container

An apparatus in which release material is applied to a heated fuser member. A back up member is in communication with the fuser member and a sheet of support material having particles thereon passes therebetween. The particles on the sheet of support material contact the fuser member. The apparatus reciprocates a bar of release material into and out of contact with the fuser member. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to be limiting as to the scope of the invention in any way.
