Abstract
The present invention provides a fixing apparatus includes a fixing roller, a heating sourcefor allowing the outer peripheral surface of the fixing rollerto have a given temperature capable of performing a fixing operation, a pressing rollerin rotational contact with the fixing roller, and a biasing memberfor allowing the pressing rollerto be brought into press contact with the fixing rollerat a given pressure. The fixing apparatus is operable to allow a sheet with a surface supporting an unfixed toner thereon to pass through the rotational contact region along one direction so as to fix the unfixed toner onto the sheet. In this fixing apparatus, the fixing rolleris disposed on the side of the sheet surface supporting the unfixed toner, and the pressing rolleris disposed on the opposite side of the fixing rollerwith respect to the sheet. Further, the biasing memberis adapted to apply a biasing force to the pressing roller in a direction Y intersecting with an axis X connecting the respective center positions of the fixing rollerand the pressing roller
