Title:
電子写真感光体、プロセスカートリッジ及び画像形成装置
Document Type and Number:
Japanese Patent JP6690602
Kind Code:
B2
Abstract:
An electrophotographic photosensitive member (100) includes a conductive substrate (101) and a photosensitive layer (102) having a single-layer structure. The photosensitive layer contains a charge generating material, an electron transport material, a polycarbonate resin, and a hole transport material. The electron transport material includes a compound having a halogen atom and represented by general formula (1), (2), (3), (4), or (5). The polycarbonate resin has a terminal group having a fluoro group and represented by general formula (10). The hole transport material includes a compound represented by general formula (20), (21), (22), (23), (24), (25), (26), or (27). A charge of calcium carbonate as measured by charging the calcium carbonate through friction with the photosensitive layer is at least +6.5 µC/g. The photosensitive layer has a Vickers hardness of at least 17.0 HV at 45°C.
