摘要： A method of preparing a photoconductor drum having an overcoat layer is provided. The photoconductor drum is used in an electrophotographic image forming device. The photoconductor drum is prepared from a curable composition including a urethane resin having at least six radical polymerizable functional groups and a charge transport molecule having at least one radical polymerizable functional group. The amount of the urethane resin having at least six radical polymerizable functional groups in the curable composition is about 35 percent to about 65 percent by weight. The amount of the charge transport molecules having at least one radical polymerizable functional group in the curable composition is about 35 percent to about 65 percent by weight. This overcoat layer improves wear resistance of the photoconductor drum without negatively altering the electrophotographic properties, thus protecting the photoconductor drum from damage and extending its useful life.
