摘要： An organic laminated photosensitive material of the positive charging type comprises an electroconductive substrate (1), a charge-transporting layer (2) formed on the substrate (1) and a charge-generating and transporting layer formed (3) on the charge-transporting layer (2). The charge-transporting layer (2) is composed of a binder resin containing a hole-transporting substance, and the charge-generating and transporting layer (3) is composed of a binder resin containing a charge-generating substance and a hole-transporting substance. In this laminated photosensitive material, an excellent sensitivity is maintained even if the topmost charge-generating layer has a large thickness, and therefore, high surface saturation charge voltage and excellent printing resistance can be maintained in addition to increased sensitivity.

摘要： An image forming apparatus (11) includes a charge removing device (20) for removing the residual charge on a photosensitive film (12). The light emitted from an optical source of the charge removing device is selected from the range between the wavelengths which correspond to half of the maximum absorbance in a light absorbance characteristic of the photosensitive film (12). Since carrier generation does not occur by the light emitted by the charge removing device, the charging ability and the charge retaining ability of the photosensitive film are improved, and the image quality is significantly improved.
摘要翻译：图像形成设备（11）包括用于去除感光膜（12）上的残余电荷的电荷去除装置（20）。从电荷移除装置的光源发射的光从对应于光敏膜（12）的光吸收特性中的最大吸收的一半的波长之间的范围中选择。由于由电荷移除装置发射的光不会发生载流子产生，所以感光膜的充电能力和电荷保持能力得到改善，并且图像质量显着提高。

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。
