  • Publication number: 20120328346
    Abstract: A glossing device includes a heater member, a stripper member, an endless rotary belt, a pressure member, and a belt cooler. The heater member is subjected to heating. The stripper member is disposed parallel to the heater member. The endless rotary belt is looped for rotation around the heater member and the stripper member in a longitudinal, conveyance direction of the belt. The pressure member is disposed opposite the heater member via the belt. The heater member and the pressure member press against each other via the belt to form a glossing nip therebetween. The recording medium after passage through the nip remains in contact with the belt as the belt moves from the heater member toward the stripper member, and separates from the belt as the belt passes around the stripper member. The belt cooler is disposed adjacent to the belt to cool the belt.

  • Patent number: 8331839
    Abstract: A gloss applicator, disposed downstream from a fusing device for fusing a non-fused image on a recording medium, includes a pair of pressure units, an endless belt, and a belt suction unit. The pair of pressure units define a gloss nip therebetween through which the recording medium is passed to enhance glossiness of the fused image. The endless belt, disposed in one of the pressure units in an extended loop configuration, transports the recording medium thereon. An outer face of the endless belt can contact the fused image on the recording medium. The belt suction unit, disposed inside the endless belt loop, exerts suction on the endless belt to locally deform a given portion of the endless belt and separate the recording medium from the endless belt at the given portion as a separation position.
