Abstract

A method to make an improved organic photoconductor drum of an electrophotographic image forming device is provided. The improved organic photoconductor drum is prepared using a curable composition including a charge transport molecule containing four radical polymerizable functional groups of the general structure exemplified below:where R1 and R2 contain a spacer group and a radical polymerizable functional group, R3 and R4 are 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 R5 and R6 contain a spacer group and a radical polymerizable functional group.
