摘要： The electrophotosensitive material in accordance with the present invention containing a layer which contains polycarbonate as a binding resin and of which glass transition temperature is not lower than 62°C. This layer is excellent in adhesion to the foundation. This layer may be a photosensitive layer containing a m-phenylenediamine compound as a charge transferring material, or a photosensitive layer containing a m-phenylenediamine compound and a perylene compound as a charge generating material. The present invention also provides a photosensitive layer of which the amount of residual tetrahydrofuran is adjusted to a predetermined value or less, thereby to prevent the photosensitive layer from being decreased in sensitivity due to ultraviolet rays or visible ray.
摘要翻译：根据本发明的光电敏感材料含有含有聚碳酸酯作为粘合树脂并且玻璃化转变温度不低于62℃的层。该层与基础的粘附性优异。该层可以是含有作为电荷转移材料的间苯二胺化合物或含有间苯二胺化合物和苝化合物作为电荷产生材料的感光层的感光层。本发明还提供了将残留四氢呋喃的量调节至预定值以下的感光层，从而防止感光层由于紫外线或可见光而导致灵敏度降低。
