Electrophotographic photoreceptor and image forming method, apparatus and process cartridge therefor using the photoreceptor

摘要

An electrophotographic photoreceptor including an electroconductive substrate; and a photosensitive layer located overlying the electroconductive substrate, wherein an outermost layer of the electrophotographic photoreceptor is a crosslinked layer, obtainable by forming a layer comprising the following components and crosslinking the components:
a urethane oligomer having a radical polymerizing functional group; and
a radical polymerizing compound having one functional group with a charge transporting structure, or
a radical polymerizing oligomer having a polyester structure;
a radical polymerizing compound having three or more functional groups without a charge transporting structure; and
a radical polymerizing compound having one functional group with a charge transport structure, and
€ƒ€ƒ€ƒwherein the outermost layer has an elasticity power not less than 41 %.
