An organic photoconductor drum includes a support element, a charge generation layer over the support element, a charge transport layer over the charge generation layer, and an overcoat layer. The overcoat layer includes a curable composition having both a non-radical polymerizable additive and a charge transport molecule containing four radical polymerizable functional groups exemplified as:

##STR00001##

where R.sub.1 and R.sub.2 contain a spacer group and a radical polymerizable functional group, R.sub.3 and R.sub.4 are hydrogen atoms, and R.sub.5 and R.sub.6 contain a spacer group and a radical polymerizable functional group wherein the spacer group of R.sub.1, R.sub.2, R.sub.5, and R.sub.6, is an ethyl group and the radical polymerizable functional group of R.sub.1, R.sub.2, R.sub.5 and R.sub.6 is an acrylate group. The non-radical polymerizable additive may be a surfactant. The curable composition may also include a curing agent.
