  • Patent number: 9188917
    Abstract: An image forming apparatus includes: a fuser unit, which includes a heating member heated by a heat source and a backup member; a temperature detector; and a control unit, which starts print control when a detected temperature reaches the fixing temperature while the temperature of the heating member is increasing to a fixing temperature, and which performs decreasing control when the detected temperature reaches a predetermined temperature higher than the fixing temperature. In a case that an increasing rate of the detected temperature at the beginning of the print control is equal to or less than a predetermined value, the control unit controls the heat source so that a heat quantity radiated from the heat source during the decreasing control becomes larger than that in the case that the increasing rate of the detected temperature at the beginning of the print control is larger than the predetermined value.

  • Patent number: 9116485
    Abstract: In an image forming apparatus, a heating member for heating a recording sheet and a pressuring member disposed below the heating member are supported by a fixing unit frame. A noncontact temperature sensor disposed facing the heating member detects a temperature of the heating member without contacting the heating member. An upper frame covers an upper portion of the heating member and an upstream portion of the heating member in a conveying direction of the recording sheet. A plate-shaped upper sheet guide protrudes upstream in the conveying direction from an upstream end of the upper frame and extends in a width direction perpendicular to the conveying direction and to a vertical direction. The upper sheet guide and a lower sheet guide disposed below and facing the upper sheet guide the recording sheet in the conveying direction toward the heating member and the pressuring member.

  • Patent number: 8755707
    Abstract: An image forming device has a heating member, a thermal detecting unit, and a control unit. The heating member is positioned at an ambient temperature and heated by a heat source. The heating member fixes a developed image to a recording sheet. The thermal detecting unit is provided separately from the heating member. The thermal detecting unit detects a first temperature. The control unit uses a function to calculate a second temperature of the heating member on the basis of the detected first temperature. The control unit controls the heat source on the basis of the second temperature. The function has a rate of change that increases with decreasing the ambient temperature.

  • Patent number: 8594523
    Abstract: In an image forming apparatus, a temperature of a heating member heated by a heat source to fix a developer image on a recording sheet is detected by a temperature sensor disposed apart from the heating member. A controller controls the heat source based upon a temperature determined mathematically by application of a specific function to the temperature detected by the temperature sensor. In the controller, the specific function is switched among a plurality of functions according to a control mode which is switchable among a plurality of modes and in which operation of the heat source is regulated.

  • Publication number: 20130121738
    Abstract: A fixing device includes a frame, a pressure arm pivotably supported on the frame, and a nip release lever supported on the pressure arm. The pressure arm can release pressure contact between a heating roller and a pressure roller. The nip release lever can move between a pressing position and a release position so as to move the pressure roller between a position at which the pressure roller applies pressure to the heating roller and a position at which the pressure roller applies no pressure. The nip release lever can be halted in the release position.

  • Patent number: 8401428
    Abstract: A fixing device is mounted on a main casing of an image forming apparatus. A heating member contacts a recording medium to apply heat thereto while rotating. A heating member includes a roller that rotates about an axis. A frame supports the heating member and includes a frame fixing part that is fixed to the main casing to mount the frame on the main casing. A detecting unit opposes the heating member in an opposing direction to detect a temperature of the heating member and is separated from the heating member. A support member supports the detecting unit. A position of the support member in the opposing direction with respect to the frame is determined at a position closer to the frame fixing unit than the detecting unit. A position of the support member in an axial direction of the roller with respect to the frame is determined at a same position as the detecting unit in the axial direction.
