Abstract
An electrophotographic photoreceptor includes: a conductive base, a photosensitive layer provided on the conductive base, and a protective layer provided on the photosensitive layer. The protective layer is an acrylic resin or methacrylic resin that is a cured body of a photocurable composition including a photocurable compound and a photopolymerization initiator. A ratio of a value of a maximum peak in a wavenumber range of 1420 cm−1 to 1400 cm−1 in an infrared absorption spectrum of the protective layer to a value of a maximum peak in a wavenumber range of 1950 cm−1 to 1600 cm−1 is 1.02 or more and 1.30 or less. The protective layer has an elastic work rate of 50.0% or more and 90.0% or less.
