Patent ID: 7239837

Claim:
A fixing apparatus comprising: a fixing roller; heating means for allowing the outer peripheral surface of said fixing roller to have a given temperature capable of performing a fixing operation; a pressing roller in rotational contact with said fixing roller; and a biasing member for allowing said pressing roller to be brought into press contact with said fixing roller at a given pressure, wherein said fixing apparatus is operable to allow a sheet with a surface supporting an unfixed toner thereon to pass through a rotational contact region along one direction so as to fix said unfixed toner onto said sheet, said fixing apparatus being characterized in that: said fixing roller is disposed on the side of said sheet surface supporting said unfixed toner; said pressing roller is disposed on the opposite side of said fixing roller with respect to said sheet; and said biasing member comprising a pair of coil springs applying a biasing force to said pressing roller in a direction intersecting with a plane connecting the respective center axes of said fixing roller and said pressing roller, each of the coil springs having one end engaged with a corresponding one of both ends of the pressing roller.
