  • 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.
