In one embodiment, a fuser roll for fusing toner images onto a substrate includes a substantially rigid core member, a deformable, heat conductive base layer overlaying the surface of said core member, and an outer layer supported on the base layer. The outer layer is formed of a heat conductive, conformable amorphous metal.

Amorphous metal components for a reproduction machine

Method of developing latent magnetic images obtained by reflex thermomagnetic recording. A reflex imaging member is magnetized and a latent magnetic image formed thereon by thermoremanent exposure. The imaging member is developed by contacting it with magnetizable toner particles which have been subjected to a high intensity magnetizing field such that the toner particles retain a residual internal magnetic field after removal of the magnetizing field.

Reflex imaging process with magnetic images

This invention is directed to magnetic imaging method comprising creating a latent magnetic image on a reflex imaging member, transferring the latent image by thermoremanent duplication to a durable magnetic imaging member, developing the transferred image on the durable imaging member, and transferring the developed image to a receiving member. In one embodiment the present invention involves an improved magnetic imaging method which comprises (a) erasing and subsequently magnetizing a reflex magnetic imaging member with a D.C. magnetic field at an exposure of at least about 800 gauss in a direction parallel to the preferred axis of the aligned magnetic pigment particles in the magnetic grooves of said imaging member; (b) placing a document to be copied in contact with said imaging member; (c) directing light through said imaging member to said document and back to said imaging member by imagewise reflection from said document to expose the magnetic material in said imaging member and imagewise demagnetize said imaging member; (d) separating said document from said imaging member; (e) placing said imaging member in contact with a durable magnetic recording member; (f) directing light energy on to the rear of said durable magnetic recording member to said reflex imaging member to form a latent magnetic image on said durable magnetic recording member; (g) separating said reflex imaging member from said durable magnetic recording member; (h) contacting said durable magnetic recording member with magnetic toner particles to develop said latent magnetic image on said durable magnetic recording member; and (i) transferring the developed image from said durable magnetic recording member to a receiving member.

Thermal magnetic tape duplication method employing a reflex imaging

Magnetic imaging method wherein a latent magnetic image is created on a magnetizable imaging member comprising a base or web containing a magnetizable component. After development of the latent image with a magnetic toner composition, the developed image is transferred by pressure contact to a receiving substrate and fixed thereto. The receiving substrate comprises a permanent member which has been treated with a binder and a crystalline plasticizer. The receiving substrate provides substantially improved efficient transfer of the toner particles from the imaging member to the receiving substrate.
