  • Publication number: 20160026117
    Abstract: An image forming apparatus includes an image forming device that forms an image on a recording medium with a powdery material, the image being sized so as to extend beyond an edge of the recording medium; a collecting device that collects the material that has extended off the recording medium as a result of the image forming device forming the image; and a restricting unit that controls the image forming device in such a manner that the image forming device reduces an amount of use of the material in a region of the image that extends off the recording medium to a larger degree on an outer side of the image than a side of the image near the recording medium.

  • Patent number: 9163999
    Abstract: A temperature sensor includes a front surface; a back surface; a first temperature-sensitive element and a second temperature-sensitive element disposed side by side between the front surface and the back surface; an infrared-ray absorber; and a heat-transfer inhibitor. When the temperature sensor is exposed to infrared rays that have propagated from both of a front-surface side and a back-surface side of the temperature sensor, the infrared absorber heats up by absorbing the infrared rays and transfers heat to the first temperature-sensitive element and the heat-transfer inhibiter inhibits heat transfer to the second temperature-sensitive element caused by the infrared rays.

    Abstract: An image forming apparatus includes a rotating fixing unit, a switching unit, and a control unit. The rotating fixing unit has a surface, the surface fixing a toner image on a recording medium by contacting the recording medium. The switching unit switches between transportation directions in which the recording sheet is transported such that an orientation of a predetermined side of the recording medium with respect to the fixing unit matches either an orientation corresponding to a first direction in which the central axis of the fixing unit extends or an orientation corresponding to a second direction that is perpendicular to the first direction. The control unit controls the switching unit such that the recording medium is transported in a direction corresponding to a smaller one of integration values obtained along the first direction and the second direction.

  • Patent number: 8862040
    Abstract: A fixing device includes a fixing member that is rotatable and heated by a heater; an endless belt member that is rotatable while being in contact with the fixing member; and a pressing member that is disposed inside of the belt member. The pressing member presses the fixing member with the belt member therebetween so as to form a fixing nip between the fixing member and the belt member, the fixing nip allowing a recording medium to pass therethrough to fix a toner image onto the recording medium. In an output region of the fixing nip from which the recording medium is output from the fixing nip, a curvature of a cross-sectional shape of an end portion of the belt member in a width direction is larger than a curvature of a cross-sectional shape of a middle portion of the belt member in the width direction.

  • 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.

    Abstract: The invention provides an imaging optical system comprising, in order from an object side to an image side thereof, a first lens group of positive refracting power, a second lens group having positive or negative refracting power and a third lens group of positive refracting power. The optical system includes an aperture stop located between an object-side surface in the first lens group and an object-side surface in the second lens group. The lens on the most object side of the first lens group and the lens on the most image side of the third lens group remain constantly fixed, and upon focusing from a far distance to a near distance, only the second lens group moves axially. The third lens group comprises a front lens subgroup of positive refracting power located on the object side and a rear lens subgroup of negative refracting power located on the image side, with the largest axial air separation in the third lens group interposed between them.
