Abstract
An image heating apparatus includes (i) a heater having an elongated base member, first and second resistors extended on the base member in a longitudinal direction thereof, an electrical connecting portion, adjacent one end of the base member, for electrically connecting the first and second resistors, first and second electrodes provided only adjacent the other end of the base member and electrically connected with the first and second resistors, respectively, wherein the first and second resistors generate heat by electrical energy supplied between the first and second electrodes, (ii) a film slidable relative to the heater and (iii) a back-up member for forming a nip with the heater with the film therebetween, wherein a recording material is passed through the nip, and an image on the recording material is heated by the heat from the heater through the film, while the recording material is passed through the nip. The first and second resistors are within a width, in a direction of movement of the recording material, of the nip.
