  • Patent number: 10983465
    Abstract: An image forming apparatus, including: an image forming portion that forms an image on a recording material based on image data; a fixing portion that includes a heater having a plurality of heat generating members arranged in a direction perpendicular to a conveying direction of a recording material, and that fixes the image to the recording material using heat of the heater; a storage portion that stores history information on the recording material when image forming operation is performed in which the image forming portion forms the image and the fixing portion fixes the image, a control portion that sets power to be supplied to the heat generating members based on the history information before a type of the recording material on which the image is formed or content of the image data of the image to be formed on the recording material is determined.

  • Patent number: 9405258
    Abstract: An image forming apparatus includes a storage unit, a conveyance unit, an opening, and a movement unit. The storage unit stores, in an apparatus body of the image forming apparatus, a sheet having an image. The conveyance unit conveys the sheet having the image to the storage unit. The opening exposes the stored sheet to an outside of the apparatus body. The movement unit is movable to a first position where the sheet conveyed to the storage unit can be stored in the storage unit and a second position. The stored sheet is moved when the movement unit moves from the first to the second position, and is stopped in an exposed state where a part of the sheet is exposed to outside the apparatus body from the opening. The movement unit moves from the second to the first position when the sheet is in the exposed state.

  • Patent number: 7827829
    Abstract: An elastic fabric useable for covering pillows, seats, mattresses and the like is disclosed. The fabric is formed from elastic yarns having a breaking elongation greater than 60%, a rate of elastic recovery after 15% elongation of more than 90% and a stress at 10% elongation greater than 150 N/5 cm and less than 600 N/5 cm oriented in a direction parallel to the elastic yarn, and a rate of hysteresis loss between 20% and 45%. The fabric may be woven or knitted and provides a stable, comfortable feeling for sitting or reclining and deforms when supporting weight but returns readily to its undeformed shape.
