Abstract
Provided is a conductive belt in which a time-dependent fluctuation in electrical resistance value is suppressed even in long-term use. The conductive belt is a conductive belt for electrophotography, including: a matrix containing polyester; and a domain containing polyether ester amide, in which the conductive belt further includes a particle containing a silicone resin; the domain further contains a salt that can dissociate into a cation and an anion; and the anion has a predetermined structure.
