Abstract

Bare metal fuser rolls utilizing reactive polymer fluids for the release of electroscopic toner have been described in the prior art. In certain instances wrinkling of the substrate, e.g., paper, bearing toner images to be fused has been ob-served when the toner images are fused thereon in the bare metal fuser roll system. This problem appears to be a func-tion of the roughness of the fuser roll surface.

FUSER ROLL HAVING ROUGH SURFACE Proposed Classification

Bare metal fuser rolls utilizing reactive polymer fluids for
the release of electroscopic toner have been described in the
prior art. In certain instances wrinkling of the substrate,
e.g., paper, bearing toner images to be fused has been ob~
served when the toner images are fused thereon in the bare
metal fuser roll system. This problem appears to be a func-~
tion of the roughness of the fuser roll surface.

Elimination of the substrate wrinkling problem has been accom-~
plished by controlling the roughness of the surface of the
fuser member. Polishing and sand blasting techniques have
been attempted but precision surface roughness is difficult to
specify and control by these techniques.

In accordance with the present disclosure the desired rough~
ness of 'the fuser roll surface is attained by providing a
pattern in the surface material of the fuser roll. Preferred
patterns are random designs or very fine (high frequency)
geometric patterns. The patterns are formed in the metal of
the fuser roll surface by conventional embossing techniques.
The embossing of the fuser roll provides control of and repro~
ducibility of the roughness of the surface.
