Abstract
A fusing station including an externally heated deformable fuser roller and a relatively harder pressure roller, the fuser roller including a heat distribution layer. A fuser roller embodiment includes a core member, a base cushion layer around the core member, a heat storage layer around the base cushion layer, a heat distribution layer around the heat storage layer, and a thin gloss control layer around the heat distribution layer. Ratios of thermal conductivity divided by thickness for the layers are, respectively: for the base cushion layer, less than approximately 13.3 BTU/hr/ft /°F.; for the heat storage layer, approximately between 300 BTU/hr/ft /°F.-1400 BTU/hr/ft /°F.; for the heat distribution layer, approximately between 600 BTU/hr/ft /°F.-4,800 BTU/hr/ft /°F.; and, for the gloss control layer, approximately between 600 BTU/hr/ft /°F.-6,000 BTU/hr/ft /°F.
