摘要： An image fixing apparatus controls temperature of a rotating member for fixing with compensation for delay by using a Smith predictor with a controlled object model to reduce temperature ripple effectively. In one example, the image fixing apparatus includes a pair of rotating members to form a nip portion, a heater to heat the rotating member, a temperature sensor to detect temperature of the rotating member, a calculator to calculate a heat value to attain a target temperature of the rotating member, a controller to control the heater based on a calculation result of the heat value with compensation for delay using a model according to the calculation result, and a selector to select a control in which an output of the compensation is input into the calculator or a control in which the output of the compensation is not input into the calculator.

摘要： A fixing unit includes a rotatable fixing member and a rotatable pressure applying member. The rotatable fixing member has a heat generating layer to generate heat when subject to a magnetic flux. The rotatable pressure applying member contacts the rotatable fixing member and applies pressure to the fixing member. The rotatable fixing member and the rotatable pressure applying member form a nip therebetween, to which a recording medium is passed through to fix an image on the recording medium. The rotatable fixing member includes a magnetism regulating layer deformable when subject to pressure from the rotatable pressure applying member.

A recording medium passes through the conveyance passage unit. The fixing device fixes a toner image onto the recording medium. The optical sensor includes a light-emitting device and a light-receiving device to detect smoothness of the recording medium according to strength of light received. The fixing condition adjuster adjusts fixing conditions according to the smoothness detected. The regulator is disposed in the conveyance passage unit to regulate conveyance of the recording medium, such that at least a part of the recording medium passes through an irradiated area including an intersection that is determined by an emission angle of a first optical axis of light emitted by the light-emitting device and a reflection angle of a second optical axis of light received by the light-receiving device.
