Abstract:
Provided is an electrophotographic photosensitive member including a support and a photosensitive layer formed on the support, in which the photosensitive layer includes a phthalocyanine crystal containing a compound satisfying the following formulae (A) and (B) in itself: 8.9≦δP≦10.7 (A) and −3.2≦L≦−1.5 (B) (in the formula (A), δP represents a polar term of Hansen Solubility Parameters, and in the formula (B), L represents an energy level (eV) of an LUMO (lowest unoccupied molecular orbital) obtained as a result of structural optimization calculation based on density functional calculation B3LYP/6-31G).
