Abstract
An image fixing apparatus includes a heater which is stationary during an image fixing operation, a linear heat generating layer and a film movable in sliding contact with the heater in which a toner image on a recording material is heated by heat from the heater through the film. The heater produces amounts of heat which are different in a direction transverse to a direction of movement of the recording material by varying the resistance distribution of the linear heat generating layer.
