  • Patent number: 9382089
    Abstract: A paper transporting device includes a driving roller member, a driven roller member, a first guiding member and a second guiding member. The driving roller member is rotated. The driven roller member is rotated in contact with the driving roller member. The first guiding member is disposed on a driving roller member side, and guides a paper to a contact portion in which the driving roller member and the driven roller member are in contact with each other. The second guiding member is disposed on a driven roller member side, and guides the paper to the contact portion. The second guiding member partially protrudes inward in a radial direction of the driving roller member from an outer peripheral surface of the driving roller member at a downstream side in a paper transporting direction of the contact portion.

  • Patent number: 8712302
    Abstract: A fixing device includes a rotatable heating member including a heat source and a pressure-applying member pressed against the heating member. The pressure-applying member includes a band-shaped member that extends in a width direction of a medium that passes through a fixing area, a support member opposed to the heating member with the band-shaped member disposed therebetween, and a pressing member including a base-end portion supported by the support member and a free-end portion that extends toward the fixing area. The pressing member has urging portions arranged with intervals therebetween in the width direction. The urging portions are elastically deformable in accordance with a thickness of the medium when the medium passes through the fixing area. The free-end portion urges the band-shaped member toward the heating member so that the band-shaped member is pressed against the heating member.

  • Patent number: 8644747
    Abstract: A heating device including a heating member that heats a recording medium; a pressure unit that applies pressure to the heating member; and a rotation member that is mounted to the heating member. The rotation member is rotated upon receiving an external force and the heating member is rotated along with a rotation of the rotation member by a frictional force between the heating member and the rotation member.

  • Publication number: 20120230718
    Abstract: A fixing device includes a heat fixing member including a base body that is elastically deformable and applies heat to a medium; a press fixing member that applies pressure to the medium, a contact moving member that moves at least one of the heat fixing member and the press fixing member between a pressurizing position and a depressurizing position; a temperature detector disposed so as to face a position between an intersection of a first imaginary line and an outer surface of the heat fixing member and an intersection of a second imaginary line and the outer surface, the first imaginary line connecting a center of a fixing region and a rotation center of the heat fixing member, the second imaginary line passing through the rotation center and being perpendicular to the first imaginary line; and a temperature controller that controls a temperature of the heat fixing member.

  • Publication number: 20120155932
    Abstract: A heating device includes: a heating member that heats a recording medium; a pressure unit that applies pressure to the heating member; and a rotation unit that is mounted to the heating member and is rotated upon receiving an external force, wherein the heating member is rotated along with a rotation of the rotation unit by a frictional force between the heating member and the rotation unit generated due to deformation of at least one of the rotation unit and the heating member.
