Zusammenfassung:PURPOSE:To obviate generation of cracks in a protective layer and photosensitive layer even at the time of curing of the protective layer and to obtain excellent durability in generation of wear and flaws by sliding by containing a specific curable resin in the protective layer. CONSTITUTION:The protective layer of an electrophotographic photoreceptor 1 having a conductive base, photosensitive layer and surface protective layer in this order contains the curable resin obtd. by reaction of the monomer or oligomer of the curable resin and a bisphenol compd. The monomer or oligomer of the curable resin is preferably the monomers or oligomers, etc., of a melamine resin, acrylic resin and epoxy resin and the monomer or oligomer of the melamine resin is more particularly preferable. The average degree of polymn. of the monomer or oligomer of the melamine resin is 1 to 4 and the weight average mol.wt. of thereof is preferably
