Patent ID: 8119252

Claim:
A transferring and conveying tandem electroconductive endless belt that is driven by a drive unit to convey a recording medium held by electrostatic adsorption through four types of image-forming units so that toner images are transferred onto the recording medium, comprising: a substrate and a conductive filler, the substrate including a thermoplastic polyalkylene naphthalate resin and at least two types of thermoplastic resins having an ester bond other than the thermoplastic polyalkylene naphthalate resin, wherein the weight ratio of the thermoplastic polyalkylene naphthalate resin to the at least two types of thermoplastic resins having an ester bond is in the range of 95:5 to 55:45, and the at least two types of thermoplastic resins having an ester bond include at least one amorphous thermoplastic resin and at least one crystalline thermoplastic resin, and wherein the thermoplastic polyalkylene naphthalate resin comprises a polybutylene naphthalate resin.
