Abstract
A charge transport molecule containing four radical polymerizable functional groups used in an overcoat for an organic photoconductor drum of an electrophotographic image forming device is provided. The charge transport molecule containing four radical polymerizable functional groups of the general structure exemplified below: where Rand Rcontain a spacer group and a radical polymerizable functional group, Rand Rare selected from the group consisting of a radical polymerizable functional group, a non-radical polymerizable functional group, and one each of a radical polymerizable functional group and a non-radial polymerizable functional group, and Rand Rcontain a spacer group and a radical polymerizable functional group.
