Electrophotographic photoreceptor, image forming apparatus and process cartridge for image forming apparatus

摘要

An electrophotographic photoreceptor including an electroconductive substrate, a photosensitive layer, and a cured protection layer, wherein the cured protection layer comprises a cured material of a tri- or more functional radical polymerizable compound and a filler exposed from the surface of the cured protection layer which comprises a bump along the surface of the filler, and wherein the cured protection layer has a thickness (T) larger than a diameter (2r) of the filler therein and the following relationships (a) is satisfied: (the number of the fillers present to a depth of T/2 from a free surface of the cured protection layer/the total number of the fillers in the cured protection layer)×100>=7%(a).
