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 containing an oxygen atom of the general structure shown below: wherein R1 and R2 contain a spacer group and a radical polymerizable hydrophilic functional group containing an oxygen atom, R3 and R4 are a non-radical polymerizable functional group, and R5 and R6 contain a spacer group and a radical polymerizable hydrophilic functional group containing an oxygen atom. The curable composition may also contain at least one optional curing agent.
