ABSTRACT:
The present invention provides a fixing apparatus includes a fixing roller12, a heating source14for allowing the outer peripheral surface of the fixing roller12to have a given temperature capable of performing a fixing operation, a pressing roller16in rotational contact with the fixing roller12, and a biasing member18for allowing the pressing roller16to be brought into press contact with the fixing roller16at 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 roller12is disposed on the side of the sheet surface supporting the unfixed toner, and the pressing roller16is disposed on the opposite side of the fixing roller12with respect to the sheet. Further, the biasing member18is 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 roller12and the pressing roller16.
