Abstract: An intermediary transfer belt having surface resistivity ρs of 1×109 Ω/square or more and volume resistivity ρv of 1×1012 Ω·cm or less includes a thermoplastic resin material containing carbon black. The carbon black contained in the thermoplastic resin material has a weight ratio of 22.5-28.5 weight % and include first carbon black and second carbon black. The first carbon black of the carbon black contained in the thermoplastic resin material has a weight ratio of 50-90 weight % and dibutyl phthalate absorption of 93-127 ml/100 g, and the second carbon black of the carbon black contained in the thermoplastic resin material has a weight ratio of 10-50 weight % and dibutyl phthalate absorption of 36-79 ml/100 g.
