Abstract
An electrophotographic belt including: a base layer, an elastic layer formed on the base layer, and a surface layer formed on the elastic layer. The surface layer contains a binder resin and polytetrafluoroethylene particles. A content of the polytetrafluoroethylene particles is 200 parts by mass or more with respect to 100 parts by mass of the binder resin. The polytetrafluoroethylene particles have a number average particle diameter of 200 nm or less.
