The surface layer is in contact with the image carrier and the cleaning member. The base layer disposed at a position more apart from the image carrier and the cleaning member than the surface layer. The surface layer is provided with grooves formed by transferring a predetermined mold shape and extending in a first direction along a moving direction of the transfer belt in an operating state. The arithmetic average roughness of the surface layer in a predetermined region is less than or equal to 0.2 μm.
