ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS |
| 摘要 |
An electrophotographic photosensitive member includes an undercoat layer, the undercoat layer having a volume resistivity of from 1×1010 Ω·cm to 1×1013 Ω·cm, the undercoat layer contains (A) a zinc oxide particle and (B) at least one particle selected from titanium oxide particles coated with tin oxide doped with any one of zinc, aluminum, fluorine, tungsten, niobium, tantalum, and phosphorus and a titanium oxide particle coated with oxygen deficient tin oxide, and the content of the particle (B) in the undercoat layer is from 3% by mass to 20% by mass based on the content of the particle (A). |

1. An electrophotographic photosensitive member comprising:
a support; an undercoat layer on the support; and a photosensitive layer on the undercoat layer, wherein the undercoat layer has a volume resistivity of from 1×1010 Ω·cm to 1×1013 Ω·cm; the undercoat layer comprises: (A) a zinc oxide particle; and (B) at least one particle selected from the group consisting of titanium oxide particles coated with tin oxide doped with any one of zinc, aluminum, fluorine, tungsten, niobium, tantalum, and phosphorus, and a titanium oxide particle coated with oxygen deficient tin oxide; and the content of the particle (B) in the undercoat layer is from 3% by mass to 20% by mass based on the content of the particle (A). |
