A fusing apparatus for fixing images made from a liquid toner onto a substrate
using an electrophotographic process, the apparatus including a prefusing roller,
a backup roller positioned to create a first nip area between the prefusing roller
and the backup roller, and a fusing roller positioned to create a second nip area
between the fusing roller and the backup roller, wherein at least one of the prefusing
roller and the backup roller is heated to a temperature that provides a prefusing
temperature within the first nip area, and wherein at least one of the fusing roller
and the backup roller is heated to a temperature that provides a fusing temperature
in the second nip area that is different than the prefusing temperature of the
first nip area.
