摘要:
A fixing apparatus includes a film, a heater that contacts the inner face of the film and is capable of changing heat distribution, and a pressure member that forms the nip portion with the heater via the film, the pressure member including a region on which a diameter is increased from a center portion toward an end portion, wherein the fixing apparatus performs heater control so that a ratio of an amount of heat generation at the end portion of the heater to an amount of heat generation at the center portion of the heater is changed based on a temperature of the end portion of the pressure member, during a period at least from when the warm-up of the fixing apparatus is started until the recording material reaches the nip portion.
