Abstract:
This invention relates to image bearing member and an image forming apparatus that employs the image bearing member. The image bearing member contains an electroconductive substrate; a charge generation layer; a charge transport layer; a cross-linking surface protective layer, and a monomer having one radical polymerizable functional group with a charge transport structure. The cross-linking surface protective layer is formed by curing a monomer having at least three radical polymerizable functional groups without a charge transport structure. For the image bearing member, the ratio of the layer thickness of the cross linking surface protective layer to the layer thickness of the charge transport layer is from 0.7 to 1.3.
