Abstract
There is provided an electrophotographic photoreceptor including: a conductive support; and a photosensitive layer and a protective layer containing a cured product obtained by curing a curable compound, which are sequentially disposed on the conductive support. The photoreceptor has a Martens hardness of 255 N/mmor more. The photosensitive layer contains at least a hole transport material (HTM), and an energy difference between a HOMO level and a LUMO level of the hole transport material (HTM) is greater than 3.6 eV and 4.0 eV or less.
