PROBLEM TO BE SOLVED: To provide an electrophotographic photosensitive body having superior electrical characteristics which can provide high-quality images with the occurrence of ghost phenomenon suppressed. SOLUTION: Specially disclosed is an electrophotographic photosensitive body comprising, on a conductive support body, a foundation layer containing metal oxide particles and a binder resin and a photosensitive layer formed on the foundation layer. In this electrophotographic photosensitive body, the metal oxide particles, dispersed in a solvent obtained by mixing methanol and 1-propanol at a weight ratio of 7:3, have a volume average particle diameter of not larger than 0.1μm and a cumulative 90% particle diameter of not larger than 0.3μm, as measured by dynamic light scattering; and a compound represented by Formula (1) below is contained in the photosensitive layer. In the Formula (I), Ar<SP>1</SP>to Ar<SP>6</SP>, independently represents an optionally substituted aromatic residue; X represents an optionally substituted organic residue; and n<SB>1</SB>and n<SB>2</SB>, independently represent an integer of 0 to 2.
