    • An electrophotographic photoreceptor comprising a conductive substrate having formed thereon a photosensitive layer is disclosed, wherein said photosensitive layer contains, as a binder resin, a polyiminocarbonate resin comprising at least one of recurring units represented by formulae (I), (II) and (III): ##STR1## wherein the symbols are as defined in the specification. The polyiminocarbonate resin exhibits satisfactory solvent solubility and high compatibility with a charge transporting material and a charge generating material to provide a coating composition having satisfactory stability with time and a uniform coating film. The photoreceptor therefore has excellent electrophotographic characteristics and satisfactory productivity.
    • 公开了一种电子照相感光体,其包含在其上形成有感光层的导电基材,其中所述感光层包含作为粘合剂树脂的聚亚氨基碳酸酯树脂,其包含由式(I),(II)和(III)表示的重复单元中的至少一种 ):其中符号如说明书中所定义。(I)(II)(III) 聚亚氨基碳酸酯树脂表现出令人满意的溶剂溶解度和与电荷输送材料和电荷产生材料的高相容性,以提供具有令人满意的时间稳定性和均匀涂膜的涂料组合物。 因此,感光体具有优异的电子照相特性和令人满意的生产率。
