    • Disclosed are photoconductive elements including a conductive support, e.g., an electrically conductive film, drum, or belt, on which a negatively chargeable photoconductive layer is disposed. An electrical barrier layer is disposed between the conductive support and the photoconductive layer. The barrier layer provides a high energy barrier to the injection of positive charges, but transports electrons under an applied electric field. In embodiments, the barrier layer can transport charge by electronic mechanisms, and, is not substantially affected by humidity changes. The barrier layer includes a polyamide-co-imide having covalently bonded as repeat units in the polymer chain, aromatic tetracarbonylbisimide groups of the formula: wherein Ar1 and Ar2 respectively represent tetravalent or trivalent aromatic groups of 6 to about 20 carbon atoms, and X is O, C(CF3)2, S═O or SO2. The amount of aromatic tetracarbonylbisimide content in the polymer is selected such that the barrier layer can be coated onto the support as a relatively thick layer, which provides for enhanced performance as a photoconductor when used in an electrophotographic process.
    • 公开了包括导电性支持体(例如,导电膜,鼓或带)的光电导元件,其上设置有带负电的光导电层。 电阻挡层设置在导电支撑体和光电导层之间。 阻挡层为注入正电荷提供了高能量势垒,但在施加的电场下传输电子。 在实施例中,阻挡层可以通过电子机构输送电荷,并且基本上不受湿度变化的影响。 阻挡层包括在聚合物链中具有作为重复单元共价键合的聚酰胺 - 共 - 酰亚胺,下式的芳族四羰基双酰亚胺基团:其中Ar 1和Ar 2分别表示6至约20的四价或三价芳族基团 碳原子,X是O,C(CF 3)2,S = O或SO 2。 选择聚合物中芳族四羰基二酰亚胺含量的量使得阻挡层可以涂覆在载体上作为相对较厚的层,当用于电子照相方法时,这提供了作为光电导体的增强的性能。

    • In a photoconductive element comprising a conductive support, e.g., an electrically conductive film, drum or belt on which a negatively chargeable photoconductive layer is formed, an electrical barrier layer is formed between the support and the photoconductive layer. The barrier layer provides a high energy barrier to the injection of positive charges but transports electrons under an applied electric field. The barrier layer of the invention transports charge by electronic rather than ionic mechanisms and, therefore, is not substantially affected by humidity changes. The barrier layer comprises a polyester-co-imide, polyesterionomer-co-imide or polyamide-co-imide having covalently bonded as repeating units in the polymer chain, aromatic tetracarboxylbisimide groups of the formula: wherein Ar1 and Ar2 represent, respectively, tetravalent and trivalent aromatic groups of 6 to 20 carbon atoms.
