Abstract:
A charge transport material containing a charge transport polymer that satisfies at least one of (I) or (II) described below: (I) to independently have both a monovalent substituent having an alicyclic structure of 7 or more carbon atoms, and a monovalent substituent having a carbonyl-containing group; and (II) to have a monovalent substituent that includes a monovalent substituent having an alicyclic structure of 7 or more carbon atoms bonded directly to a carbonyl-containing group.
