Zusammenfassung:	To provide a conductive endless belt having both predetermined volume resistivity and surface resistivity in a belt circumferential direction.SOLUTION: An endless belt-shaped conductive endless belt is used in an image formation device. The conductive endless belt contains a base resin and a carbon black. The base resin is composed of a thermoplastic polybutylene terephthalate resin, a thermoplastic polybutylene naphthalate resin, and a thermoplastic polybutylene naphthalate elastomer. The average particle size of the carbon black is 15 nm or more and 30 nm or less, and the DBP oil absorption amount is 150 cm3/100 g or more and 300 cm3/100 g or less.SELECTED DRAWING: Figure 1A 【課題】所定の体積抵抗率およびベルト周方向における表面抵抗率を兼ね備えた導電性エンドレスベルトを提供する。【解決手段】画像形成装置に用いられる無端ベルト状の導電性エンドレスベルトである。基材樹脂とカーボンブラックとを含有し、基材樹脂が、熱可塑性ポリブチレンテレフタレート樹脂、熱可塑性ポリブチレンナフタレート樹脂および熱可塑性ポリブチレンナフタレートエラストマーからなるとともに、カーボンブラックの、平均粒子径が１５ｎｍ以上３０ｎｍ以下であって、ＤＢＰ吸油量が１５０ｃｍ３／１００ｇ以上３００ｃｍ３／１００ｇ以下である。【選択図】図１Ａ
