    摘要： An ink jet recording apparatus performs a print operation by controlling an ink jet recording head to eject ink drops there from against front and back surfaces of a recording sheet at a print position. The apparatus includes a transporting mechanism for transporting a portion of the recording sheet to a location outside of the apparatus after a completion of the print operation on the front surface of the recording sheet and just before printing of the back surface of the recording sheet.

    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.
