Patent ID: 8486595

Claim:
An image bearing member comprising: an electroconductive substrate; a photosensitive layer overlying the electroconductive substrate; and a protection layer overlying the photosensitive layer, the protection layer comprising a diamine compound represented by a chemical structure 1, more of the diamine compound being disposed on a photosensitive layer side than a surface side relative to a 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 A 1 , A 2 , A 3 , and A 4 independently represent (i) an alkyl group having 1 to 4 carbon atoms, (iii) a substituted or non-substituted aryl group, or (ii) —CH 2 (CH 2 ) m Z, 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 a case in which each of A 1 , A 2 , A 3 , and A 4 is (iii) is excluded, and where B 1 and B 2 represent —CH 2 —, —CH 2 CH 2 —, —CH 2 —Ar a —, —Ar a —CH 2 —, —CH 2 CH 2 —Ar a —, and —Ar a —CH 2 CH 2 —, and Ar a represents a substituted or non-substituted arylene group, where the protection layer further comprises a cured material formed by a radical polymerizable compound having a charge transport structure and a radical polymerizable compound having no charge transport structure, where the photosensitive layer comprises a laminate structure including a charge generation layer and a charge transport layer, and where the diamine compound is included in the charge transport layer.
