ABSTRACT:
A method and an apparatus for fixing an image formed by a colorant upon an image support body is described. A fluid, binder material contacts a heated transport surface. The heated surface comprises an elastomeric material which is positioned on a tubular body formed of a material having a relatively high coefficient of thermal conductivity. The transport surface advances the heated binder material to a nip formed with an adjacent pressure contact surface which is transported in moving engagement with the heated surface. The binder material at the nip temperature exhibits a viscosity which exceeds the surface energy of the elastomeric transport surface while the surface energy of the support material and the imaged surface is greater than the surface energy of the elastomer. The binder is thus transferred to the imaged surface for fixing the image thereon.
