Abstract
An electrophotographic photoreceptor according to the present invention includes a conductive support, a photosensitive layer, and a protective layer disposed in sequence. The protective layer includes a cured product of a composition containing a radically polymerizable compound, a charge transporting material exhibiting a maximal absorption wavelength of 405±50 nm, and a photopolymerization initiator of a single-molecule system; and a following Expression (A) is satisfied:G=Eox(D/D+)−Ered(A−/A)−E*≤−0.2 [eV] Expression (A):
G represents a free energy change, Eox(D/D+) represents an oxidation potential of the charge transporting material, Ered(A−/A) represents a reduction potential of the photopolymerization initiator, and E* represents an excitation energy of the charge transporting material.
