  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.

  光电导元件包括导电支架，例如导电薄膜、滚筒或皮带，在其上形成可带负电荷的光电导层，在支架和光电导层之间形成电阻挡层。阻挡层对正电荷的注入提供高能量阻挡，但在外加电场作用下可传输电子。本发明的阻挡层通过电子机制而非离子机制传输电荷，因此不会受到湿度变化的实质性影响。阻挡层由聚酯-酰亚胺、聚酯-酰亚胺或聚酰胺-酰亚胺组成，聚酯-酰亚胺、聚酯-酰亚胺或聚酰胺-酰亚胺的聚合物链中具有共价键合的重复单元，芳香族四羧基二酰亚胺基团的分子式如下： 其中 Ar1 和 Ar2 分别代表 6 至 20 个碳原子的四价和三价芳香基团。

  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, or both electronic and ionic mechanisms, and, is not substantially affected by humidity changes. The barrier layer includes a polyester-co-imides, polyesterionomer-co-imides, or polyamide-co-imides having covalently bonded as repeat units in the polymer chain, aromatic tetracarbonylbisimide groups of the formula: or 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.
