Apparatus for fusing toner images to substrates such as plain paper, said apparatus comprising:
- means for applying release agent material to a predetermined length of a heated fuser member;
- a pressure member contacting said heated fuser member;
- means for passing substrates between said two members, said substrates having a dimension less than said predetermined length which dimension defines a paper path relative to said heated fuser member;
- and
- a blade structure contacting said pressure member in an area corresponding to an area on said fuser member which is outside said paper path for preventing release agent buildup on said fuser roll in an area outside of said paper path.
