This invention provides an electrophotographic photosensitive material comprising a conductive support having thereon a photoconductive layer containing at least an inorganic photoconductor and a binder resin, wherein the photoconductive layer contains an N-hydroxyimide compound represented by the following general formula (I):
wherein Z represents an organic residue capable of forming a cyclic compound having a saturated or unsaturated bond, thereby increasing its photosensitivity and improving its chargeability, dark charge retentivity and photosensitivity over a wide range from visible to infrared regions. Upon actual reproduction, the inventive material provides a fog-free and clear image even under severe conditions such as hightemperature and high humidity conditions (e.g., 30 °C and 80 % RH).
本发明提供了一种电子照相感光材料,它包括一个导电支架,支架上有一个光电导层,该光电导层至少含有一个无机光电导体和一个粘结剂
树脂,其中光电导层含有一个由以下通式(I)表示的 N-羟基
亚胺化合物:
其中 Z 代表一种有机残留物,能够形成具有饱和或不饱和键的环状化合物,从而增加其感光性,并在从可见光到红外线的大范围内改善其电荷性、暗电荷保持性和感光性。在实际复制时,本发明的材料即使在高温高湿等恶劣条件下(如 30 °C 和 80 % 相对湿度)也能提供无雾和清晰的图像。
