US Patent 10162278 Electrophotographic photosensitive member, process cartridge and electrophotographic apparatus

Disclosed herein is an electrophotographic photosensitive member in which leakage hardly occurs even in the case of using a layer containing metal oxide particles as an electrically conductive layer in the electrophotographic photosensitive member, and which is compatible with definition in output images, the electrophotographic photosensitive member sequentially including: a support, an electrically conductive layer, and a photosensitive layer, the electrically conductive layer containing a binder material and particles represented by General Formula (1).Nb2.00O5.00-XNY  (1)(In Formula (1), Nb is a niobium atom, O is an oxygen atom, N is a nitrogen atom, and 0.00<Y<X≤4.00).
