An electrostatographic imaging member assembly including a hollow electrostatographic imaging drum having a first end and a second end, at least one coating on the drum extending to at least the first end of the drum, the coating having an outer electrostatographic imaging surface and a first drum supporting end cap mounted on the first end of the drum, the first drum supporting end cap including a disk shaped member having an annular skirt encircling an exterior surface of the first end of the cylindrical substrate, the annular skirt having an imaginary axis coextensive with an imaginary axis of the drum. This electrostatographic imaging member assembly may be fabricated by sliding the skirt of the end cap over the end of the drum with or without presoftening of the coating. The electrostatographic imaging member assembly may be utilized in electrostatographic imaging apparatus in which the end caps support electrostatographic imaging apparatus subassembly components.
