电子照相感光体、处理盒及图像形成装置
摘要：
本发明提供电子照相感光体、处理盒及图像形成装置。电子照相感光体具备导电性基体和感光层。感光层为单层，且包含电荷产生剂、空穴输送剂、电子输送剂及聚碳酸酯树脂。聚碳酸酯树脂具有通式(1‑1)所表示的重复单元以及通式(1‑2)所表示的重复单元。通式(1‑1)及(1‑2)中，Q1及Q2表示氢原子，且Q3及Q4表示烷基，或者，Q1及Q2表示烷基，且Q3及Q4表示氢原子。电子输送剂包含由通式(ETM1)～(ETM5)表示的化合物。感光层的耐刻划深度为0.50μm以下。感光层的维氏硬度为17.0HV以上。
摘要（英）：

The present invention provides an electrophotographic photoreceptor, a process cartridge, and an image forming apparatus. The electrophotographic photoreceptor has a conductive substrate and a photosensitive layer. The photosensitive layer is a single layer and contains a charge generating agent, a hole transporting agent, an electron transporting agent, and a polycarbonate resin. The polycarbonate resin has a repeating unit represented by the formula (1-1) and a repeating unit represented by the formula (1-2). In the general formulae (1-1) and (1-2), Q1 and Q2 represent a hydrogen atom, and Q3 and Q4 represent an alkyl group, or Q1 and Q2 represent an alkyl group, and Q3 and Q4 represent a hydrogen atom. The electron transporting agent contains a compound represented by the general formulae (ETM1) to (ETM5). The etch resistance depth of the photosensitive layer is 0.50 [mu]m or less. The Vickers hardness of the photosensitive layer was 17.0 HV or more.
