A metal plate for electromagnetic heating is disclosed which includes a substrate comprising aluminum or aluminum alloys, an intermediate layer formed on at least a portion of one surface of the substrate and comprising zinc or zinc alloys and a conductive layer formed on the intermediate layer for serving as a heat generating body when eddy current induced by high-frequency magnetic flux flows therethrough. Methods of manufacturing a metal plate for electromagnetic heating and a metallic mold for electromagnetic heating are also disclosed.

Induction heating plated metal mold and its manufacture

Metal plate for electromagnetic heating

A composite material comprising a magnetic metal plate and an aluminum or aluminum alloy plate, the magnetic metal plate and the aluminum or aluminum alloy plate being clad together by an axial hot pressing. A process for producing a composite material which comprises the step of: cladding a magnetic metal plate with an aluminum or aluminum alloy plate by an axial hot pressing. A process for producing a composite material molding which comprises the steps of: cladding a magnetic metal plate with an aluminum or aluminum alloy plate by an axial hot pressing thereby obtaining a composite plate material; and subsequently subjecting the composite plate material to press molding and/or stamping and cutting.

A fixing roller for use in the fixing stage of a fixing apparatus such as a copying machine provided with multiple rubber and/or fabric layers of certain thicknesses and hardnesses surrounding a core member to improve the copying characteristics of the roller.

Elastic fixing roller

An image fixing apparatus in which a recording material having an unfixed image through a nip formed between rotatable rollers. At least one of the rollers is provided with a surface layer containing straight-needle like single-crytal fibers.

Image fixing device and roller therefor having a low resistance surface

Elastic fixing roller and method of producing the same

The invention provides an elastic roller for use in an apparatus for fixing a toner image, electrostatically formed on copy paper by passing the toner image between two rollers, comprising a roller core, a fusible fluororesin layer coated on the outside of the roller core, a porous fluororesin having porous portions affixed to the roller core through the fusible fluororesin layer, and a rubber impregnated into the porous portions of the porous fluororesin. It also provides a method for making an elastic roller including the steps of fusing a fusible fluororesin layer on the outside of a roller core or base; affixing a porous fluororesin having porous portions to the roller core through the fused fluororesin layer; filling the porous portions of the porous fluororesin with a rubber after fusing the porous fluororesin to the roller core; and hardening the rubber.
