摘要:
An object is to provide a latent electrostatic image bearing member that can provide high-quality images for prolonged periods, owing to photosensitive layers and crosslinked surface layers having excellent flaw and wear resistance and appropriate electric properties, image forming method, image forming apparatus and process cartridge that employ latent electrostatic image bearing member respectively. Accordingly, provided is a latent electrostatic image bearing member that comprises a support and at least a photosensitive layer and a crosslinked surface layer disposed on the support, wherein the crosslinked surface layer comprises a reactant from radical polymerizable compounds having three or more functionalities with no charge transport structure and radical polymerizable compounds having one functionality with charge transport structure, and at least two different antioxidants.
