Electrophotographic photoreceptor, method of producing an electrophotographic photoreceptor, process cartridge, and image forming apparatus

Abstract

An electrophotographic photoreceptor includes a conductive substrate, a photosensitive layer, and a protective layer. The photosensitive layer includes a charge generating agent, a hole transporting agent, and a binder resin. The hole transporting agent has two or less chain ethene-1,2-diyl groups or no chain ethene-1,2-diyl group. The protective layer is a top surface layer of the electrophotographic photoreceptor and includes a photocurable resin. A ratio A/B of first absorbance A of the protective layer to second absorbance B of the protective layer is 0.160 or less, the first absorbance and the second absorbance being measured by Fourier transform infrared spectroscopy. The first absorbance is the highest absorbance in a wavenumber range of 1627 cm−1 or more and 1647 cm−1 or less. The second absorbance is the highest absorbance in a wavenumber range of more than 1647 cm−1 and 1800 cm−1 or less.
