    • A process cartridge is disclosed which includes an electrophotographic photosensitive member having a photosensitive layer and a charging means. The charging means has a charging member which is provided in contact with the electrophotographic photosensitive member to charge the photosensitive member electrostatically by applying a voltage formed by superimposing an alternating-current voltage on a direct-current voltage. The photosensitive member has a surface layer which contains at least one of a polyarylate resin having a weight-average molecular weight of 7.5 x 10 to 3.7 x 10 and having a specific structural unit of Formula (1) and a polycarbonate resin having a weight-average molecular weight of 7.5 x 10 to 3.7 x 10 and having a specific structural unit of Formula (2). The photosensitive member further contains fluorine-containing resin particles. Also, an electrophotographic apparatus having the photosensitive member is disclosed.
    • 公开了一种处理盒,其包括具有感光层和充电装置的电子照相感光构件。 充电装置具有充电部件,该充电部件设置成与电子照相感光部件接触以通过施加通过将交流电压叠加在直流电压上而形成的电压来静电充电感光部件。 感光构件具有表面层,该表面层含有重均分子量为7.5×10 3的聚芳酯树脂中的至少一种。 至3.7×10 4。 并具有式(1)的特定结构单元和重均分子量为7.5×10 3的聚碳酸酯树脂。 至3.7×10 4。 并具有式(2)的特定结构单元。 感光部件还含有含氟树脂颗粒。 另外,公开了一种具有感光构件的电子照相设备。 <图像>
