Patent ID: 6994941

Claim:
An electrophotographic photosensitive member comprising a conductive support and a photosensitive layer provided on the support, wherein; said photosensitive layer contains at least one charge-transporting material; wherein at least one of said charge-transporting material contained in said photosensitive layer is a charge transporting material having a structure represented by the following Formula (1) and having a molecular weight of from 1,500 to 4,000; and the charge-transporting material having a structure represented by the following Formula (1) and having a molecular weight of from 1,500 to 4,000 is held in a proportion of from 90% by weight to 100% by weight based on the total weight of the charge transporting material contained in said photosensitive layer: wherein Ar 101 to Ar 108 each independently represent a substituted or unsubstituted monovalent aromatic carbocyclic group or a substituted or unsubstituted monovalent aromatic heterocyclic group, and Z 11 to Z 15 each independently represent a substituted or unsubstituted divalent aromatic carbocyclic group or a substituted or unsubstituted divalent aromatic heterocyclic group, and wherein one of Z 11 to Z 15 in Formula (1) is a substituted or unsubstituted dibenzothiophenylene, and the balance are each a substituted or unsubstituted biphenylene group.
