  • Patent number: 10152006
    Abstract: A fixing device includes a rotatable endless belt formed into a loop and a heater disposed opposite the endless belt to heat the endless belt. A nip formation pad is disposed inside the loop formed by the endless belt. The nip formation pad includes a metallic thermal equalizer extending in an axial direction of the endless belt. A rotatable pressure rotator presses against the nip formation pad via the endless belt to form a fixing nip between the endless belt and the pressure rotator, through which a recording medium bearing a toner image is conveyed. The pressure rotator includes an increased tackiness portion disposed at a lateral end of the pressure rotator in an axial direction of the pressure rotator to transmit a driving force to the endless belt. The increased tackiness portion is disposed opposite the thermal equalizer of the nip formation pad.

  • Patent number: 10139459
    Abstract: A method using 2D multi-spectral imaging (2DMSI) for MRI imaging of a metallic object (such as a biopsy needle) and region surrounding the metallic object within an imaging field of view of an MRI apparatus includes segmenting the imaging field-of-view into spatial-spectral bins, where the segmenting is based on off-resonance frequency induced by the metallic object and slice location; selectively exciting each frequency bin of the spatial-spectral bins by inverting a slice selection gradient between excitation and refocusing pulses; performing repeated acquisition with different radiofrequency modulations to produce acquired images of adjacent bins; composing a 2DMSI image by root-sum-of-squares combination of the acquired images of adjacent bins; and highlighting in the 2DMSI image an area of furthest off-resonance bins based on 2DMSI off-resonance information by thresholding image intensity in frequency bins, thereby indicating a contour of the metallic object.

  • Patent number: 10139754
    Abstract: In a toner receiving device, an opening/closing member closes and opens the toner receiving port. The opening/closing member moves from a closing position to an opening position when attaching the toner case. The support mechanism includes a guide rail and a plurality of guide pieces and supports the opening/closing member. The guide rail includes a first rail portion and a second rail portion that are inserted between the plurality of guide pieces when the opening/closing member is at the closing position and the opening position, respectively. The first rail portion is thinner than the second rail portion so that a play in an up-down direction between the opening/closing member and the support mechanism is larger when the opening/closing member is at the closing position than when it is at the opening position.

  • Patent number: 10101416
    Abstract: The method comprises an initial cooling step (E0) during which the temperature (T_ECH) of the heat exchanger (30) is lowered and, at the same time, the flow rate of the said first flow (FLS) is set to an initial flow rate. Following the initial cooling step (E0), an operation of circulating the first flow (FLS) is initiated (E1) and during this the said first flow (FLS) passes through a heat exchange (30) at a first flow rate which is higher than the initial flow rate. The initial flow rate of the first flow may be set to zero or to a value set so that the pressure inside the said circuit is greater than or equal to the pressure outside the said circuit.

  • Patent number: 10095175
    Abstract: A developer roll includes end seal regions subject to accumulating residual toner. An adjacent photoconductive member has a longitudinal extent with a central area defining an imaging region and longitudinal ends outside the central area defining non-imaging regions. The photoconductive member has a length extending beyond a length of the developer roll so that the end seal regions of the developer roll contact the non-imaging regions of the photoconductive member. During cleaning, the non-imaging regions become charged and discharged to electrostatically attract and transfer away the toner from the end seal regions. A blade scrapes clean the toner from the photoconductive member.
