    Abstract: An endless intermediate transfer belt includes a substrate layer, and a surface layer to be disposed on the substrate layer. The surface layer is configured by a polymerized cured product of a radical polymerizable composition including a radical polymerizable monomer having a radical polymerizable functional group, an oxime ester-based photopolymerization initiator having a carbazole structure, and a metal oxide particle subjected to surface treatment. The radical polymerizable functional group corresponds to one or both of an acryloyl group and a methacryloyl group. The metal oxide particle subjected to surface treatment includes a metal oxide particle, and a substance for support, to be supported on a surface of the metal oxide particle.
