    摘要: The present invention provides an electrophotographic photoreceptor including a photosensitive layer on a conductive substrate, an outermost layer of the electrophotographic photoreceptor including a cured film of a composition which includes at least one charge transporting compound (a) having a charge transporting skeleton and at least two structural units represented by R—O—CO—CR′═CH—R″ in the same molecule, and at least one polycarbonate resin; a ratio (IA/IC) of an absorption peak intensity (IA) resulting from stretching vibration of a carbonyl group originating from the structural unit represented by R—O—CO—CR′═CH—R″ of the charge transporting compound (a) to an absorption peak intensity (IC) resulting from stretching vibration of a carbonyl group originating from the polycarbonate resin in an IR absorption spectrum of the outermost layer being from about 0.5 to about 10, and a width at half maximum of the absorption peak of the absorption peak intensity (IA) being about 25 cm−1 or more.
