To provide an electrophotographic seamless belt which is excellent in, above all, flexing resistance and attracting conveyance force, in order to cope with a small-sized, high-speed, and high-definition image forming apparatus and is capable of performing good-quality image formation.
In the electrophotographic seamless belt having a layer containing at least a thermoplastic resin, the layer containing the thermoplastic resin is subjected to calorimetry involving heating from room temperature up to 200°C at 10°C/min as first temperature raising, then temperature falling down to 100°C at -10°C/min, then heating up to 200°C at 10°C/min as the second temperature raising. During the first temperature raising, the maximum endtherm peaks within the temperature range of melting initiation temperature ±20°C and other endtherm peaks or shoulders are observed and the number of the endtherm peaks or shoulders observed within the temperature range of the melting initiation temperature ±20°C during the second temperature raising is smaller than the number of the endtherm peaks or shoulders observed within the temperature range of the melting initiation temperature ±20°C during the first temperature raising.
