Abstract
Abstract An image holding member comprises a hollow cylindrical photosensitive member provided with a photosensitive layer on the surface of a hollow cylinder and a bonding member to be bonded to said photosensitive member at the end portion thereof, said bonding member being adhered to said photosensitive member with a non-solvent type adhesive to be made into an integrated structure. An image holding member comprises a hollow cylindrical photosensitive member having a photosensitive layer on the surface of a hollow cylinder provided with a projection at substantially the central portion of said cylinder on the bottom face closed at one end of said cylinder and a supporting member having a hole fittable with said projection at the central portion which is adhered to said photosensitive member with a non-solvent type adhesive to be made into an integrated structure.
