An image bearing member including an electroconductive substrate, a photosensitive layer overlying the electroconductive substrate, and a protection layer overlying the photosensitive layer, the photosensitive layer containing a diamine compound represented by the chemical structure 1, more of the diamine compound being disposed on the photosensitive layer side than the surface side relative to the midpoint in a depth direction of the protection layer: where X represents a substituted or non-substituted arylene group, or a compound represented by a chemical structure 2: where R represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or an alkoxy group having 1 to 4 carbon atoms, where A1, A2, A3, and A4 independently represent an alkyl group having 1 to 4 carbon atoms, a substituted or non-substituted aryl group, or —CH2(CH2)mZ, where Z represents a substituted or non-substituted aryl group, a substituted or non-substituted cycloalkyl group, and a substituted or non-substituted heterocycloalkyl group, and m represents 0 or 1, and where B1 and B2 represent —CH2—, —CH2CH2—, —CH2—Ara—, —Ara—CH2—, —CH2CH2—Ara—, and —Ara—CH2CH2—, and Ara represents a substituted or non-substituted arylene group.
