  • Endless belt, heat-sealing device, fixing device, and article transfer device
    Patent number: 11359041
    Abstract: An endless belt includes a substrate layer, and a first surface layer that is disposed on an outer circumferential surface of the substrate layer and that includes a cross-linked fluororesin layer. A layer containing a cross-linked fluororesin forms the inner circumferential surface of the belt. Martens hardness of the inner circumferential surface of the belt at 130° C. is higher than Martens hardness of the outer circumferential surface of the belt at 130° C.

  • Transfer device, image forming apparatus, and endless belt
    Patent number: 11334006
    Abstract: An endless belt includes: a resin; and electrically conductive particles, wherein an integrated discharge amount is 350 ?C or less. The integrated discharge amount is determined by disposing an electrode at a position spaced 60 ?m apart from the outer circumferential surface of the belt, applying a voltage to the electrode, and measuring the amount of discharge for a period of 1 second after the voltage reaches 1300 V.

  • TRANSFER DEVICE, IMAGE FORMING APPARATUS, AND ENDLESS BELT
    Publication number: 20220146966
    Abstract: An endless belt contains: a resin; electrically conductive carbon particles; and a surfactant. When polyester resin particles having a volume average particle diameter of 4.7 ?m are caused to adhere to an outer circumferential surface of the endless belt and then air is blown onto the outer circumferential surface from an upper side of the outer circumferential surface while the blowing pressure of the air is increased, all the polyester resin particles adhering to the outer circumferential surface are separated from the outer circumferential surface before or when the blowing pressure reaches 6 kPa.
