An electrophotographic photoreceptor includes: a conductive support; a photosensitive layer disposed on the conductive support; and a protective layer disposed on the photosensitive layer, wherein the protective layer is formed of a polymerized and cured product of a radically polymerizable composition containing a radically polymerizable monomer, a perfluoropolyether compound having a radically polymerizable group, and metal oxide fine particles having a radically polymerizable group.
