摘要： The present invention provides a photosensitive body of Se-based function separation type to be used in electrophotographic equipment which employs long wavelength light for writing. Such a body exhibits outstanding abrasion resistance and heat resistance without sacrificing good electrical properties. This is accomplished by interposing an intermediate layer of As-Se alloy between the surface protective layer and the chargeable layer. The intermediate layer contains As in an increasing concentration gradient across the section of the layer from the chargeable layer to the surface protective layer. This graded As concentration causes the coefficient of thermal expansion to gradually decrease across the intermediate layer section in the direction from the chargeable layer to the surface protective layer. Thus the intermediate layer prevents the surface protective layer from thermal stress and cracking by acting as a transition buffer between the differing properties of the protective layer and chargeable layer.
摘要翻译：本发明提供一种使用长波长光进行书写的电子照相设备中的基于Se的功能分离型感光体。这种物体表现出优异的耐磨性和耐热性，而不牺牲良好的电性能。这是通过在表面保护层和可充电层之间插入As-Se合金中间层来实现的。中间层在从可充电层到表面保护层的层的跨越部分的增加的浓度梯度中包含As。该As浓度使得在从可充电层到表面保护层的方向上，中间层部分的热膨胀系数逐渐降低。因此，中间层通过在保护层和可充电层的不同性质之间充当过渡缓冲液来防止表面保护层发生热应力和开裂。
