A directly heating type fixing apparatus for use in an image forming device such as an electronic copying machine, has a heating roll which includes an heat generating electric resistance layer and a toner releasing layer both formed on the surface of a cylindrical body thereof, and a pressure roll which is arranged to contact the heating roll under pressure. Current collecting bearings made of an electrically conductive material are provided on both sides of the heating roll, respectively. These current collecting bearings and the heat generating electric resistance layer of the heating roll are electrically connected with each other.
