1. An electrophotographic mono-layer belt, comprising:
a particle containing a polymer having a fluorinated hydrocarbon group; and a silicone oil, the particle and the silicone oil being in a thermoplastic matrix resin, wherein: the particle has an average primary particle diameter of from 3 nm to 30 nm, and the polymer comprises a branched polymer that has a functional group represented by the following formula [1] at a terminal of a side chain; when a thickness of the electrophotographic mono-layer belt is represented by T, in a cross-section of the electrophotographic mono-layer belt in a thickness direction, a presence amount of silicon atom derived from the silicone oil at a surface of the belt satisfies a relationship of (presence amount of a silicon atom at surface of belt)>(presence amount of a silicon atom at 1T/2-thickness section); and the particle is dispersed in the belt in the thickness direction:where X represents a hydrogen atom or a fluorine atom, m represents 1 or 2, and n represents an integer of from 0 to 5. |
