Patent ID: 8507162

Claim:
An electrophotographic photosensitive member comprising: a conductive support; an intermediate layer provided on the conductive support; and a photosensitive layer provided on the intermediate layer and comprising a charge-generating substance and a hole-transporting substance, wherein at least one of the intermediate layer and the photosensitive layer comprises a compound represented by the following formula (1): wherein, in the formula (1), R 1 and R 2 each independently represent a hydrogen atom or a methyl group, and X represents a group having a structure represented by the following formula (X1) or (X2): wherein, in the formula (X1), R 3 to R 6 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, a halogen atom, a methoxy group, or an atomic group for forming an aromatic ring together with R n and R n+1 , n represents an integer from 3 to 5, and the aromatic ring is unsubstituted or substituted with a halogen atom, an alkyl group having 1 to 4 carbon atoms, a halogenated alkyl group having 1 to 4 carbon atoms, or a nitro group, wherein, in the formula (X2), R 7 to R 12 each independently represent a hydrogen atom, an alkyl group having a 1 to 4 carbon atoms, a halogen atom, a methoxy group, a nitro group, a halogenated alkyl group having 1 to 4 carbon atoms, or an atomic group for forming an aromatic ring together with R n and R n+1 , and n represents an integer from 7 to 11.
