摘要： An electrophotographic belt includes a base layer containing a binder resin and carbon black in the binder resin. The binder resin contains at least one resin selected from the group consisting of PEEK and PPS. A water content calculated by ((X2−X1)/X2)×100 is 0.6% where X1 is a mass of a specimen cut out of the base layer when in a nitrogen atmosphere a temperature of the specimen is increased from 30° C. to 100° C. at a rate of 20° C./min. and maintained at 100° C. for 30 min, and X2 is a mass of the specimen when in a nitrogen atmosphere the specimen is thereafter cooled from 100° C. to 30° C. at a rate of 20° C./min. and the specimen is left to stand in the air under an environment of a temperature of 23° C. and a relative humidity of 50% for 48 hours.
