Zusammenfassung: | A method of preparing an organic photoconductor drum having a protective overcoat on its outermost surface is provided. In an example embodiment, a photoconductor drum having an electrically conductive substrate, a charge generation layer, a charge transport layer and an outermost protective overcoat layer is provided. The photoconductor drum is cured using a two-step process. The first curing step applies either ionizing irradiation, such as with an electron beam or by gamma rays or applies non-ionizing irradiation such as ultraviolet light to the photoconductor drum. A mask is sized and placed over the print area of the initially cured photoconductor drum, thereby exposing the outermost edges of the photoconductor drum. The outer edges of the masked photoconductor drum is then exposed to a second curing step using ultraviolet light irradiation. |
