Patent ID: 7376377

Claim:
A conductive endless belt used for a tandem type transfer and transport system in which the conductive endless belt is circularly driven by a drive member so as to transport a recording medium held by the belt using electrostatic adsorption to four types of image forming members, and in which respective toner images provided thereon are sequentially transferred onto the recording medium, the conductive endless belt comprising: a base material selected from the group consisting of (a) a thermoplastic polyamide resin, (b) an acrylonitrile-butadiene-styrene resin, (c) a thermoplastic polyacetal resin, (d) a polymer alloy or a polymer blend containing at least two of the resins (a) to (c), and (e) a polymer alloy or a polymer blend containing at least one of the resins (a) to (c) and a thermoplastic resin; a high molecular weight ionic conductive agent; and a fluorinated surfactant, wherein an addition amount of the fluorinated surfactant is in the range of 0.01 to 20 parts by weight relative to 100 parts by weight of the base material.
