ABSTRACT:
A sheet or web material for use in developing and fixing toner images which comprises a support and a thermo-adhesive fixing layer defining the surface of the material on which the toner image is deposited. The thermo-adhesive fixing layer comprises an organic polymeric material and has the following properties: a surface resistance above 10.sup.10 Ohm/square, freedom from blocking at least up to 35.degree. C, a melt viscosity at 190.degree. C of not more than 120 P, and an abrasion resistance at 20.degree. C above 175 g.
The process for fixing a toner image on this sheet or web material comprises the steps of image-wise depositing on said thermo-adhesive fixing layer toner particles forming with the molten thermo-adhesive fixing layer a contact angle smaller than 90.degree., heating above 90.degree. C at least those parts of such layer corresponding with the toner images, said heating being of a sufficient intensity and duration that said particles sink within the softened fixing layer, and allowing said imaged layer to cool to fix said image particles in said layer.
