  • Patent number: 10474076
    Abstract: A fixing device fixes a toner image onto a piece of paper by conveying the piece of paper formed with the toner image while nipping the piece of paper at a fixing nip, and includes: an endless belt that is rotated; a pressing member that presses the belt; a support member that supports the pressing member; a sheet wound around the pressing member along the conveyance direction; and a pressurizing member that forms the fixing nip with the belt, wherein a part of an upstream region of the sheet existing more on an upstream side in a winding direction than a contact region contacting the belt and the pressing member and a part of a downstream region of the sheet existing more on a downstream side in the winding direction than the contact region are interposed between the pressing member and the support member, and are fixed by pressing force.

  • Patent number: 9170537
    Abstract: A fuser for fixing an unfixed toner image on a recording material includes: an endless belt body heated by a heat source; a pressing body moved to be connected to and disconnected from an inner peripheral surface of the belt body; a pressure roller member making pressure-contact with the pressing body through the belt body; a tension body moved to be connected to and disconnected from the inner peripheral surface of the belt body, contrary to the connection and disconnection movement of the pressing body; and a rotation transmitting unit configured to transmit a rotational force of the pressure roller member to the belt body using the tension body, while the pressing body is separated from and the tension body makes contact with the inner peripheral surface of the belt body.

  • Patent number: 8521050
    Abstract: A first temperature is obtained based on an amount of infrared rays incident upon a lens of an infrared temperature sensor, and a second temperature is obtained based on a temperature of a thermistor. A system controller performs first temperature control when a detected temperature difference between the first temperature and the second temperature is less than a predetermined temperature difference, performs second temperature control when the detected temperature difference is equal to or greater than the predetermined temperature difference, and activates an alarm when an elapsed time during which the second temperature control is continuously executed has become equal to or greater than a time that is the sum of a first predetermined time and a second predetermined time.

  • Patent number: 4826879
    Abstract: An ocular antihypertensive composition for topical use which contains an effective amount of a compound represented by the formula ##STR1## or a salt thereof having, in low concentrations, intraocular pressure lowering activity in mammals, low toxicity and no influence on the pupil size and, therefore, is useful as a therapeutic agent for glaucoma, for instance.Furthermore, since the compound is effective in low concentrations, the possibility of tolerance development is considered to be scarce.
