摘要： A photoconductor with a charge transport layer having about 20-25% by weight of 4-N,N-bis(4-methylphenyl)-amino-benzaldehyde-N′,N′-diphenylhydrazone is in an essentially standard resin binder, such as a polycarbonate resin binder. Electrical characteristics are those of the larger amounts using conventional charge transport agents, and the larger amount of binder provides much improved wear resistance and consequently longer useful life of the photoconductor. Charge transport layers with only the foregoing bis-methyl material do exhibit moderate fatigue upon exposure to light. However, this can be overcome by adding 0.5% or less of a fluorenyl-azine as a light absorber, specifically 9-(p-diethylaminobenzylidenehydrazono)fluorene, in the charge transport layer. No antioxidant is required for electrical stability improvement.

摘要翻译： 具有电荷输送层的感光体具有约20-25重量％的4-N，N-双（4-甲基苯基） - 氨基 - 苯甲醛-N'，N'-二苯基腙，为基本上标准的树脂粘合剂，例如 聚碳酸酯树脂粘合剂。 电气特性是使用常规电荷传输剂的较大量的电特性，并且较大量的粘合剂提供了大大改善的耐磨性并因此延长了光电导体的使用寿命。 仅具有上述双甲基材料的电荷输送层在暴露于光时确实表现出适度的疲劳。 然而，通过在电荷输送层中加入0.5％以下的芴基吖嗪作为光吸收剂，特别是9-（对二乙基氨基亚苄基亚肼基）芴可以克服这一点。 电气稳定性改善无需抗氧化剂。
