摘要:
An oil application apparatus (1) comprising a porous oil-holding member (2), a heat-resisting fiber felt, and an oil application amount control layer. The porous oil-holding member (2) is impregnated with silicone oil. The heat-resisting fiber felt has a bending resistance in the range of 30 to 90mm and is provided on an oil application side of the porous oil-holding member (2). The oil application amount control layer is provided on the oil application side of the heat-resisting fiber felt.
摘要:
An oil application roller has a core shaft (12) and an oil retention/supply layer (14) formed to cover the outer peripheral surface of the core shaft (12). The oil retention/supply layer (14) includes a porous elastic material which exhibits no substantial swelling against an offset-preventing oil used, and is impregnated with a mixture containing an offset-preventing oil and a curable oil-retention material. The curable oil-retention material is cured.
摘要:
A release agent composition for use in an electrophotographic process is disclosed. This composition includes a specifically-defined heat-stable silicone oil-silicone wax random copolymer. The copolymer has a melting point such that it is liquid on the hot fuser roll, but solidifies at room temperature on the printed page. A random silicone copolymer, in the form of a paste or pliable caulk, which is useful for sealing leaks in toner cartridges is also disclosed. Finally, the method for preparing these copolymers is disclosed.
摘要:
Fluoroelastomer surfaces (2) for fuser members (1) and a method for fusing thermoplastic resin toner images to a substrate using fuser surfaces, including a method for forming these surfaces which includes dissolving a fluoroelastomer; adding an amino silane to form a resulting homogeneous fluoroelastomer solution; and subsequently providing a layer of the homogeneous fluoroelastomer solution to the supporting substrate (4).
摘要:
A fusing system, method of fusing with a fuser member (1) having a thermally stable FKM hydrofluoroelastomer surface (2) for fusing thermoplastic resin toners to a substrate (12) in an electrostatographic printing apparatus has a polyorgano T-type amino functional oil release agent, the oil having predominantly monoamino functionality per active molecule to interact with the hydrofluoroelastomer surface to provide a substantially uniform interfacial barrier layer to the toner and a low surface energy film to release the toner from the surface.
摘要:
A fusing device for fusing a toner image by passing a recording sheet carrying an unfused toner image by means of the torque of a heating roll through a nip portion between the rotating heating roll and a heat-resistant solid elastic member which is forced to contact the outer peripheral surface of the heating roll to form the nip portion. In the fusing device, the heat-resistant solid elastic member includes an elastic body penetrated with a liquid release agent, and a lease-agent penetration control film whose region which is used for covering the surface of the elastic body and corresponds to at least the nip portion is formed of a porous film.
