A photoconductive element of smooth surface comprises a single aggregate photoconductive layer which contains an aggregate photoconductor and at least three organic charge transport agents. In a preferred embodiment the aggregate photoconductive composition is formed from a high molecular weight alkylidene diarylene polycarbonate and is mixed with at least five organic charge transport agents and the element is overcoated with a thin, smooth, abrasion-resistant layer of silicon carbide. The smooth surface of the photoconductive element has a 20° gloss greater than about 6 and is resistant to scumming by fine toner particles.
