  • Patent number: 10429776
    Abstract: A controller of an image heating apparatus executes a first heater control operation, when a sheet having a width such that the sheet passes both a position of a first temperature detector and a position of a second temperature detector, is heated in a nip, for controlling power supply to a heater so that a temperature detected by the second temperature detector is maintained at a heater target temperature, and a second heater control operation, when a sheet having a width such that the sheet passes through the position of the first temperature detector, but does not pass through the position of the second temperature detector, is heated in the nip, for controlling the power supply to the heater, so that the temperature detected by the first temperature detector, irrespective of the temperature detected by the second temperature detector, is maintained at a film target temperature.

  • Publication number: 20180329340
    Abstract: An image heating apparatus includes a cylindrical film, a heater, a roller forming a nip with the film, a first temperature sensor in a first area of the film passed by a minimum width sheet that is capable of being fed by the apparatus, a second temperature sensor in a second area of the heater which is outside an area to be passed by a minimum width sheet and which is passed by a maximum width sheet, a third temperature sensor in a third area of the heater outside the second area, and a controller. When a large width sheet is heated, the controller executes a first heater control responsive to the temperatures detected by the first temperature sensor and by the second temperature sensor. When a small width sheet is heated, the controller executes a second heater responsive to the temperature detected by the first temperature sensor only.

  • Patent number: 10031449
    Abstract: An image heating apparatus for heating an image on a recording material. A controller executes a first heater control so that a temperature detected by a second temperature detecting element is maintained at a target temperature of the heater. The controller executes a second heater control for controlling the heater so that a temperature detected by a first temperature detecting element is maintained at a target temperature. When the first heater control is executed, the controller corrects the target temperature of the heater in accordance with the temperature detected by the first temperature detecting element, and when the second heater control is executed, a feeding speed of a recording material in a nip is less than that when the first heater control is executed.

  • Publication number: 20060137319
    Abstract: Fiber materials (for example, yarns, knitted goods and woven goods) are provided which sustain texture characteristics of a natural fiber such as silk, are effectively prevented from yellowing over time due to light or sweat, are less contaminated with a residual toxic gas, and are effectively prevented from worsening in warmth retention and strength over time, but which can be produced at a lower cost. More specifically, the fiber materials having improved qualities required for clothes are obtained by bringing a chemical fiber containing 0.01 to 5.0% by weight of titanium oxide together with a natural fiber.
