A heating apparatus includes a cylindrical film and a pressing element that rotates with the cylindrical film and forms a nip with the cylindrical film. A medium is conveyed through the nip from an upstream side to a downstream side. The heating apparatus further includes a heater arranged inside the cylindrical film and on which a heating element is disposed. An upstream end of the heater is located downstream of an upstream end of the nip, and a downstream end of the heater is located downstream of a downstream end of the nip.
